Bluetooth Prioritization

[scoutconnor]

I have a BT headset and BT in my car.
Is there any way to have my phone stay connected to the headset until it is in the car, at which point it chooses the car by itself? I use BT in the car for music so I really need my phone connected to it and doing so automatically would be optimal, otherwise, I'll just have to remove the headset while in the car (Moto Hint)

Maybe with Automate — automatic tasks or Tasker, not natively, as far as I know.
