Rather than have devices on my main screen, I am trying to program "rooms."

My question is how do I go to the previous page? For example, if I am in the living room, and I select cable box, do my business, how do I return to the living room page without saying "living room."

It is relevant when I am in the bedroom and I select the "cable box" and I want to return to the bedroom page. The cable box page is the same one for both living room and bedroom, so I would hate to just have to duplicate the pages.

Thanks!!!!
