I start with a choose your location page. When you choose your location it jumps to the most common source (cbl/sat) the startup macro resides on this button. Hitting the home button from here will take you to the source selection page of whatever zone you are in. Hitting home again will take you back to choose your location page.

I also only have 1 remote in ID all remotes are exactly the same. That way if I change something I dont have to do it multiple times. I have not tried this yet with Zigbee but I dont see what it would not work.
