Bluetooth Proxy in Companion app for fixed devices

I’ve got a few fixed devices running the companion app (wall tablets, an Android TV I sideloaded the app onto, etc.)
While I expect it would be awful for battery life on an actual mobile device, it’d be fantastic if I could use the BT radios in those devices that are otherwise useless as BT proxies for HA as an optional feature in the companion app.

Apologies if this FR already exists, I searched and didn’t see anything.

This is not the companion app, but Theengs mobile app can already push decoded BLE data to a MQTT broker

Companion app has ble transmitter, i believe they are same in this sense.

But companion app doesn’t act as active proxy, just forwarding ble signals.
