Push to talk indicator

Is there a way we can get a push to talk indicator? Perhaps our icon is a different color or something?

I spend the better part of 10 minutes trying to diagnose a mic issue and I had somehow hit my key binding for push to talk. But if there was a different color indicator somewhere I would have realized it was my finger fumble that did it.

And the test mic doesn't help as it still works just fine on push to talk.
