Any way to know which player clicked a dialog?

If you have a trigger with the event "a dialog button is clicked for <dialog>", is there any way to know which player clicked the dialog? It seems Triggering Player doesn't work for this event.

That's right. Use the dialog engine to avoid exactly this problem.
