Yikes @Mike_Marx, you're right.
Even more embarrassing is that it looks like we broke this a while ago. I'm sorry that no one noticed until now, Mike, but we appreciate you taking the time to post about it.
It looks like the feature works in 3.4.1 (Windows/macOS), so you can downgrade to that if you would like. Otherwise, we will get it fixed ASAP.
I'm sorry again for the trouble, Mike, but thank you for reporting it!
