Power Query - Create multiple COUNT columns in a single Power Query line of code

Hi,

I have successfuly made a COUNT based on Group By columns. See below for the snippet that works.
#"NoO_Removed Other Columns" = Table.SelectColumns(Source,{"Partition", "Invoice Date", "Branch Name"}),
#"NoO_Grouped Rows" = Table.Group(#"NoO_Removed Other Columns", {"Partition", "Invoice Date", "Branch Name"}, {{"Number of Orders", each List.NonNullCount([Partition]), type number}}),

 

What I would like to do now is COUNT a number of individual columns by the same Group By. I can do this separately and then merge the individual COUNTS together, however I would like to achieve the result using a single line of code. I am having trouble achieving this. Below is my snippet of code that is failing:

 

#"NoO_Removed Other Columns" = Table.SelectColumns(Source,{"Partition", "Invoice Date", "Branch Name", "Postcode", "DMS Place"}),
#"NoO_Grouped Rows" = Table.Group(#"NoO_Removed Other Columns", {"Partition", "Invoice Date", "Branch Name"}
                                                                                                                                                                         {{"Number of Orders", each List.NonNullCount([Partition]), type number}},
                                                                                                                                                                         {{"Count of Postcode", each List.NonNullCount([Postcode]), type number}},
                                                                                                                                                                         {{"Count of DMS Place", each List.NonNullCount([DMS Place]), type number}}
                                                                                                                                                                         ),

 

The error I'm getting is:
-------------------------------------------------------------------------------
Expression.Error: We cannot apply indexing to the type List.
Details:
Value=List
Index=List
-------------------------------------------------------------------------------


Can it actually be done?  If yes, then what do I need to change in my failing snippet of code?

Thanks in advance.
