Premiere Pro and a Bluetooth headset...

[#1]

So when I start editing a project and I forget to turn on my Bluetooth headset, then I turn it on, the audio from the project doesn't automatically switch to the headset.  Similarly, if I'm using a headset and, say, it goes dead so I switch to another headset, the audio from the Premiere Pro project doesn't come through on the new headset.  I have to close Premiere Pro and re-load it, and then it will use the new headset.

How do I get Premiere Pro to use the sound device that the computer is using -- WITHOUT closing and re-opening Premiere Pro?  Kinda stupid that it doesn't do this automatically -- it should use whatever speakers the computer is using, automatically.
