Sending audio to PCP player via Bluetooth - bluez-alsa?

I can't find the answer to this anywhere.

I want to pair my phone, or other bluetooth device to my PCP player (PI Zero with BT) and have the ability send audio out via my Justboom amp hat whilst keeping the squeezeplayer function alive

Surely that is possible using bluez-alsa? If so can I pair via SSH if not currently supported in GUI?
