Blueprint triggers with an arbitrary number of entities?

I’m trying to make a blueprint that doesn’t have a set number of entities triggering it.

Specifically, I’ve got an input selector for input_booleans and I’d like to be able to just select multiple booleans with the same selector and then trigger if ANY of them are “on”.

I’ve seen a few hacks around the forums regarding setting up multiple selectors, defaulting to “None” and then checking if they’re set. Is this the only solution?
