Any House Ownership Trigger

[Rocksocks]

I'm trying to figure out how to set a trigger where whatever house crosses a waypoint will take ownership of a building. I've gotten the waypoints to work for a single house if it crosses the line but I can't figure out how to make a trigger that allows any house to cross and will give ownership of the building to the house that crosses. Any ideas how to link multiple triggers for potential ownership to a building? It seems I can only link 1 house and there should be some capability to add the triggering house gains ownership.
