Is there a way to drive a dashboard combobox off of write security at an upper level Entity member? The combobox contains level 3 members that I'd like to limit via planner security. The idea being PlannerA sees just the level3 members that are assigned to his group, PlannerB sees the level3 members that are assigned to her group, etc.
