Add USB and Bluetooth channels in the config tab

Hello,

All is in the title. I spent a lot of time trying how to use the Bluetooth channel as a USB stereo output because it was only available in the processing tab.

It would be more consistent if the Bluetooth and the USB channels were present in the config tab as well, so that we could configure all the channels at the same time.

Thanks for reading,

Cyril.

Bluetooth isn’t available as output.
