Option to not store connections in Address Book

I'd like the option to not store every connection in my address book in RealVNC Viewer. When I search, I only want my cloud connections to show up and not every random IP address that I've connected to when something is on a test bench. If I replace a PC with a machine with the same name, I don't want two entries to show up in the search, but because it stored the old connection it shows up twice.
