Feature request: mute proximity notifications for a specified device

If I install Bitchat in all my devices, each device will regularly get "X bitchatters are nearby" notifications, which isn't helpful as the other devices are all me. I'd like to be able to silence these alerts by marking a device in the settings.

I guess the ultimate solution would be sharing an identity across devices so they can all be used separately yet are never treated as different users -- but I assume that would be a big undertaking.
