There should be an ability with in the slicer to remove blanks from leaf nodes while using ragged hierarchy

I am aware that there are custom hierarchy slicers that provide us the ability to remove blanks from leaf nodes but when using bigger hierarchies with hierarchy levels around 20, the custom visuals are having performance issues like slower loading, freezing and sudden shut off of power bi.
On the other hand, the existing power bi slicer works very fine with such large hierarchies, but doesn't have ability to remove leaf node blanks. If that feature is added in the slicer, it would be a great enhancement. Thanks.
