Is it possible to see triggers work while playing (not recording) a scene?

I'd like to rehearse my trigger moves before I actually record them. I notice that triggers don't fire when just playing a scene, they only work when the scene is paused or recording.

Ideally, I'd be able to run through the scene and practice my moves. I know a work around is to do it in record mode, then undo. A minor, but annoying workflow hiccup...

Am I missing something? Is there a way to play through the scene and see the results of hitting triggers?
