You can't disable the built-in "On collision with another object" event, but with my behavior you can know the UID of the instances that are colliding, so technically you can use that to ignore collisions between specific instances. I think that you probably need like a list of UID of which the collisions must be ignored. It is no big deal, I can add this functionality, maybe it can be useful for some use cases. You will be able to add N UIDs to the "black list" with a string like: "1,2,3" and be able to remove them with the same method, like "2,3". Could this work?
