Detached Garage

Hi, I currently have a Ring system for my house. I would like add a second control panel for my detached garage so that I can arm the detached garage at night while not arming the house. I have spoken with several people at customer service and they tell me that I would not be able to do this because they can't manage two control panels at the same address. FYI I was willing to pay for both control panels. Can someone give me a further explanation? I would like to continue with Ring but will be forced to switch if this can not be resolved. Thanks!
