Multiple base stations at same location - Celluar backup available for both?

I’ve read numerous posts on this topic, but still need a little clarification on functionality with respect to the Protect plans. I understand only one base station per location/address can be setup on the professional monitoring service. My question is, if I setup a secondary base station in my detached shop(same address) will that station be able to take advantage of the cellular backup service if it’s registered to the same location as the main(pro monitored) station? I realize this secondary shop system will have to be self-monitored, but I’d like to still have the capability of cellular backup.
