    First thing that comes to my head is this..
    Duplicate the Table and remove all but columns B and E and filter it to just "Yes"

    Then, merge this table back to your main table using column B

    Expand column E(from table 2) and rename it to make it a little more clear.
    Use this new column and only filter for "Yes"

Insert this code where #"Changed Type" should be replaced with your previous step

= Table.Combine(List.Select(Table.Group(#"Changed Type", {"ColumnB"}, {{"All", each _}})[All], (x)=>List.Contains(x[ColumnE], "Yes")))

Complete test code in action for testing

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCk8sSS1S0lEyNDIGksGlxYl5QDo7JSs7BUgrxeoglJiYmoGUlKSWpQLptNTUwtRCmJrgxLwUAkoIGBOZWoyizNzCEkg65iWCFKWkpaDZhCqdkoZkQmJeZUlGZl46LkNiAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ColumnA = _t, ColumnB = _t, ColumnC = _t, ColumnD = _t, ColumnE = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ColumnA", type text}, {"ColumnB", Int64.Type}, {"ColumnC", type text}, {"ColumnD", type text}, {"ColumnE", type text}}),
    #"Grouped Rows" = Table.Combine(List.Select(Table.Group(#"Changed Type", {"ColumnB"}, {{"All", each _}})[All], (x)=>List.Contains(x[ColumnE], "Yes")))
in
    #"Grouped Rows"
