Unique and consecutive values count and list to one string

Question

Here is the thing. Maybe due to of all the (probable) possibilities I can't figure out exactly how to do the following. My preference is to do it via the query editor (M). This to I can (re)use and maybe modify it for other projects:&nbsp;&nbsp;Table is called 'Data'&nbsp;Names&nbsp;&nbsp;&nbsp;&nbsp; ValueNameB&nbsp;&nbsp;&nbsp;&nbsp; XNameB&nbsp;&nbsp;&nbsp;&nbsp; XNameA&nbsp;&nbsp;&nbsp;&nbsp; YNameB&nbsp;&nbsp;&nbsp;&nbsp; YNameC&nbsp;&nbsp;&nbsp;&nbsp; XNameC&nbsp;&nbsp;&nbsp;&nbsp; X&nbsp;&nbsp;Desired operations/functions:1. Look for all unique Names and count them consecutively and list them in CountCONS2. Look for alle unique Names and count the total of occurences and list them in CountALL3. Add (in consecutive order) CURRENT&amp;ALLPREVIOUS&nbsp; Values into one string and list them in ValuesCONS behind every row4. Add (in consecutive order) ALL the Values into one string and list them in ValuesALL behind every row5. Look for the values "X" AND "Y" in ValuesALL and if both are found at least 1 time (no matter the order) list "YES" in column Combination otherwise "NO"&nbsp;Desired output:Names&nbsp;&nbsp;&nbsp;&nbsp; Values&nbsp;&nbsp;&nbsp;&nbsp; CountCONS&nbsp;&nbsp;&nbsp;&nbsp; CountALL&nbsp;&nbsp;&nbsp;&nbsp; ValuesCONS&nbsp;&nbsp;&nbsp;&nbsp; ValuesALL&nbsp;&nbsp;&nbsp;&nbsp; CombinationNameB&nbsp;&nbsp;&nbsp;&nbsp; X&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; X&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XXY&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; YESNameB&nbsp;&nbsp;&nbsp;&nbsp; X&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XX&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XXY&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; YESNameA.&nbsp;&nbsp;&nbsp; Y&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Y&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Y&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; NONameB.&nbsp;&nbsp;&nbsp; Y&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XXY&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XXY&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; YESNameC.&nbsp;&nbsp;&nbsp; X&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; X&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XX&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; NONameC.&nbsp;&nbsp;&nbsp; X&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XX&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XX&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; NO&nbsp;I've already used many googled variants with COUNT/COUNTX/FILTER/SUMMARISE/FILTER etc the last 2 days. but I got 'lost in translation'. Maybe a bit extensive, but maybe many others can be helped by this as well.&nbsp;Hope you can help.

Sure:&nbsp;let
    Source = Data,
    AddedOriginalSort = Table.AddIndexColumn(Source, "OriginalSort", 1, 1),
    Grouped = Table.Group(AddedOriginalSort, {"Names"}, {{"GroupedData", each _, type table}, {"CountALL", each Table.RowCount(_), type number}, {"ValuesALL", each Text.Combine([Value]), type text}}),
    AddedCountCONS = Table.TransformColumns(Grouped,{{"GroupedData", each Table.AddIndexColumn(_,"CountCONS",1,1)}}),
    ExpandedGroupedData = Table.ExpandTableColumn(AddedCountCONS, "GroupedData", {"Value", "OriginalSort", "CountCONS"}),
    OriginalSort = Table.Sort(ExpandedGroupedData,{{"OriginalSort", Order.Ascending}}),
    RemovedOroginalSort = Table.RemoveColumns(OriginalSort,{"OriginalSort"}),
    AddedValuesCONS = Table.AddColumn(RemovedOroginalSort, "ValuesCONS", each Text.Start([ValuesALL],[CountCONS])),
    AddedCombination = Table.AddColumn(AddedValuesCONS, "Combination", each if Text.Contains([ValuesALL],"X") and Text.Contains([ValuesALL],"Y") then "YES" else "NO"),
    ReorderedColumns = Table.ReorderColumns(AddedCombination,{"Names", "Value", "CountCONS", "CountALL", "ValuesCONS", "ValuesALL", "Combination"})
in
    ReorderedColumns
