Is it possible to disable a filter based on another selection? We have several campuses, and want to be able to report by Systemwide as well as by campus. However, if I select "Systemwide", the "College" filter becomes meaningless because of how they are organized and I'd like it disabled, only to be enabled when a specific campus is selected. I know I could do this by making a separate "Systemwide" tab with systemwide selected and college filter deleted, but that seems like a bad solution. Any tips?
