Bluetooth - how to make Apple TV/Companion choice stick

Is there a way to make the Zwift app (running on an Apple TV), instead of using the ATV BT, choose the Companion app to bridge BT connections for the trainer and HR monitor, or at least give me a choice? My HR strap ran out of battery charge, so I decided to not use the Companion that day. Next time, it took all kinds of gyrations to force the BT connections back to the Companion app. Eventually, it asked me and I was back in business. Thanks for any tips.
