Option to restrict Enable.Doorbell.Trigger to just one device
**Is your feature request related to a problem? Please describe:**
I'd like the ability to limit the Enable.Doorbell.Trigger to one device, namely my G4 Doorbell.  I currently have 11 Protect devices around my house, and when I have the doorbell trigger option enabled it creates a On/Off device for every single camera which I really don't want - It'd be great if you could limit it by MAC address like you can do with the video and audio options to allow me to have it just for the Doorbell itself!  Also just curious but why was it changed from a contact sensor to a switch?  In my mind a contact sensor makes more sense as that's effectively what it is!

**Describe the solution you'd like:**
Specify by MAC address

**Describe alternatives you've considered:**
None come to mind
