Ignore BSP in trace?

I’m using the top down template as a playground for testing things. But I’m quickly getting annoyed at the default control setup. I want to ignore the pillars when the player clicks to set next destination.

I have a custom trace channel called Input. I’ve set default to blocking. I’ve set the traces in the controller blueprint to the Input channel. Now how do I set the pillar BSPs in the default scene to not be blocking? I don’t see a collision section on any of the BSPs, so does that mean they automatically block everything by default?

I’m aware that I’ll be able to click through the “floor” after this change but I can take care of that later. First I just want to be able to click the area behind the pillars and actually move there.
