Hi, 
I love this feature! I've had so many cases that could have been solved throughout the years.
Implementing this now to remove gathering data from various Excel files, having users fill in their information directly in Powerbi > a database, however it would be great to be able to work with dropdown lists:

The button slicer cannot be styled as a dropdown list, which makes it a bit difficult to work a nice design when having a few options to manipulate. It is not possible to make dependent a normal slicer with a button slicer. so a dropdown list option would be great instead of just Tiles and Tabular
