Hide Colum in a Matrix

Hi all,

I have the following Matrix:

When I write a measure it looks like following:

How can I hide the column measure in 2018/4?

I dont want just BLANK... that is not nice... the heading remains than and it takes space.

Go to the column header on the right side and just drag to the left to make it smaller also dont work... the dates are choosen by a slicer... choosing 2018/4 and 2018/3 doesnt work than... than the measure for 2018/4 would be hided instead of 2018/3.

Is that problem solvable? :robotfrustrated:
