Camera Quick Toggle in iOS app

When I’m looking at one cam on my iPhone app, I’d like to be able to quickly switch to a nearby cam if I see something. For example, if someone walks by the front door, being able to click a button to see the side door without ending live, exiting that cam, going back to the list, choosing which cam, and THEN restarting live on the neighboring area. I realize streaming two is probably too much for most connections - but skipping all the exiting and beginning the menu again would save time when I want to see why someone is in a certain area.
