Sort by column value and not sum of rows column value

[Fragan]

Hello,

I have this matrix : 

Im sorting the matrix by Col1 in Descending order, it is sorting by sum of col1 in each line.

What i want to do it when i click on a month it sort it by col1 in this specific month. (For example when i click on juin i want to have category 2 row then category 1 row).

Anyone knows how i can achieve this ?

@Fragan , that is not possible on Matrix as on now.

It sorts on Row totals
