Unity - setting default environment on static objects

Question

Hey ya'll, I'm currently trying to add some reverb zones to my game.

A lot of objects (like doors) don't need to make any noise until I call, say, an "Open" audio event on them. However since our door wasn't an AKGameObj when the player started, it never received an OnTriggerEnter call from its containing environment trigger and thus never got configured to be part of the right aux bus.

Going through and adding a useless script that manually adds each potentially sound emitting object to the proper environment on start seems like an incredibly bad idea.Have I missed something? How should this be handled?

Thanks!
