Ue4 building system: how to remove duplicate box collisions

I don’t think you under stand what I’m going for. Imagine this: I have an actor, Lets call this actor 1, Then I place a floor next to actor 1, lets call this actor 2. When I’m looking at actor 1 I want to disable the collision in actor 1 and delete the collision in actor 2 if its a duplicate. Or if there is a way I could destroy the duplicate component on spawn/beginplay.
