Automatic Notification/Ringtone Toggle

The toggling in Notification Behavior -> Block Notifications/Ringtones works perfectly however, I was wondering if there's a way to automate it when a device connects. As I understand it, based on my experience, you must manually change the behavior to and back each time you connect or disconnect a bluetooth device. Is this accurate? I also run Llama, so if there's an intent I can capture from the app, that would be helpful too.
