Dynamic Column Headers with Dates

[GE1]

For some reason I can't find the way to change the name of a column in a table or matrix dynamically. I can change the table title with a function, but not the column names.

I have a table (or matrix) with measures as the columns:
Column 1 is current month; Column 2 is previous month; Column 3 is the difference between Cols 1 and 2; Column 4 is 12 months ago; Column 5 is the 12 month average.

I want the names of the columns to change each month. So they would say:
Jul 24; Jun 24; Month Change; Jul 23; Aug 23-Jul 24 Average.

Obviously, next month they would say:
Aug 24; Jul 24; Month Change; Aug 23; Sep 23-Aug 24 Average.

Other than sticking cards over every column name(!) how can I do this?

Thank you

You will need to use a calculated table to generate these column names during each semantic model refresh.
