Cross-Table Sorting Multiple Dynamic Columns

I've built a cross table with months as the columns, costs as the body and names on the Y-axis.

The months being used changes as I filter down to my current view. 

I would like to be able to sort Column1, Column2, Column3, etc...... 

Sometimes Column1 could be Jan-2018, but it could also be May-2019, depending on my current filter. 

Is there a way to accomplish this?
