Grouping hide some countries at filter on level 3

[Anonymous]

Hi everyone, 

I created a sales district hierarchy into three parts. Now I want to hide some countries at level 3 that are not part of the groups in order to show the country just ones at the filter, but "" doesn´t fit.

Any suggestions to hide a cell or to adapt the filter?

Many thanks in advance!

Use a different hierarchy slicer visual, one that supports ragged hierarchies.
