PowerApps: Visualize filter in Queries

Is there a way to add columns Programically to many queries?

Labeled Summary of all queries

let
    Source = Record.RemoveFields(
        #sections[Section1],
        "AllQueries", MissingField.Error
    ),
    Summary = Record.ToTable( Source ),
    OnlyTables = Table.SelectRows(
        Summary, each Value.Is( [Value], Table.Type )
    ),
    #"Add Query Id" = Table.AddIndexColumn(OnlyTables, "Query Id", 0, 1, Int64.Type)
in
    #"Add Query Id"

Random Power Query

• 

• 

Power Query Sugar for selecting distinct filters. If the condition is not true, then it throws an error. Name = "Orders" works because it results in a distinct value from the column Name It’s valid even though the final query is many records. It’s the “distinctness” of the filter that is required to be true

Source{ [Name = "Orders", Signature = "table"] }
