I have some data, lets say city names and I have a slicer on this data.
I want to pin a tile on my dashboard with the following slicer configurations:
- Visual with city A, B, C
- Visual with all other cities (excluding A,B,C)
The problem is that the data set changes, so there are new cities all the time. They should be automatically included on the second visual. If I click `select all` on the slicer it works, but as soon I deselect A,B,C `select all` is automatically deselected.
That's not bad, at least I can preconfigure that. But now the slicer only has two values (true/false or whatever name I give it). How to show the slicer with the original values, but when new values are added they are auto-selected?
