this is my rough draft, 
i think it kinda matches what you were saying.
if you click on the little audio adjust icon it takes you to a more detailed page with that zone . .

again, 
just a rough draft.
this is my first attempt at a custom da system.
(i used to only do advanced zone 2 systems or sonos systems)
its a very simple system using a sonance matrix/amp solution with two way feedback.

now i just gotta look through those pages and find icons for the zones.


thanks!
