M query help to generate data table with hourly rows in addition to existing table

Hi, 

I have got below data as shown in image

To get above datatable, i have used below query

let
    TodaysDate = Date.From(DateTimeZone.FixedUtcNow()),
    Ranges = {
                {"1D", 
                TodaysDate, 
                TodaysDate, 
                1},
                {"WTD", 
                Date.From(Date.StartOfWeek(TodaysDate)), 
                TodaysDate, 
                2},
                {"MTD", 
                Date.From(Date.StartOfMonth(TodaysDate)), 
                TodaysDate, 
                3},
                {"QTD",
                Date.From(Date.StartOfQuarter(TodaysDate)),
                TodaysDate,
                 4},     
                {"YTD", 
                Date.From(Date.StartOfYear(TodaysDate)), 
                TodaysDate, 
                5},
                {"1W", 
                Date.AddWeeks(TodaysDate,-1) + #duration(1,0,0,0), 
                TodaysDate, 
                6},
                {"4W", 
                Date.AddMonths(TodaysDate,-1) + #duration(1,0,0,0), 
                TodaysDate, 
                7},
                {"LY", 
                Date.AddYears(TodaysDate,-1) + #duration(1,0,0,0), 
                TodaysDate, 
                8}
             },
    GetTables = List.Transform(Ranges, 
            each CreatePeriodTable(_{0}, _{1}, _{2}, _{3})),
    Output = Table.Combine(GetTables)
in
    Output

Now the question, i have is i want to generate the file including all the hours starting form the first date in datatable. Similarly, the fist column must state whether it is part of 1D (one day) group, 1W (1 week) group & Month to date (MTD) , quarter to date QTD & year to date (YTD). I am using this to ultimately create a time slicer tile, based on which dashboard user will select the time. Another slicer which is not part of the details which i shared, will actually do the aggregation of the data, e.g day, week, month etc. I managed to get this sorted, but what i missed is Hour part, For single day selection, user want to see the data in hourly, which in current datatable wont possible, 

Please help/guide me generate code in M query where the table contain 24 rows for every date & every group, so that i can club it when required. Hope i managed to explain my problem statement well. TIA
