"Exclusion" Assignments to Apps

Hey! I know we can accomplish this through rules, (If in this group, and not this person, assign this rule), but I’d LOVE if we had an exclusions tab as well as an assignments tab in the GUI for Apps. That way I could assign an App to “Everyone” but then exclude “InfoSec” for example, or “Everyone” and exclude “UK Office” or even “Engineering” but not “x person in Engineering”
