[Bug]: Custom zone per camera selection
### Describe the bug

I have custom zone created for one camera. I have totally 3 Nest camera connected in my home and used in home bridge. The problem is that custom zone is replicated to all Nest camera motion sensors of all 3 cameras, rather the one. Is there a way to limit custom zone to a single camera?
