Maybe this functionality is already there and I just don't know how to do it.
For example, I have 6 cameras total on my property. There are times, such as when I order food delivery, that I want to just view two particular cameras, my driveway and my front porch. However, those cameras are number 1 and number 6, so the only option I've found is to use multiview to view all of the cameras at once.
I would mainly like this in the mobile app, but I don't know if that would also require an underlying change to the server app.
Anyway, just thought I'd throw that out there, If it's already possible by a configuration change somewhere, please let me know.
