Why not do a pop up with flags?
I just did one for zone vol control
available from any page on the remote.

Make the pop up visible via flags only.
Male the button that activates the pop up
set the flag and make a small x on the pop up
that clears the flag.

I actually used the home button to trigger the pop up
( if you hold it down for 1 seconds it sets the flag that then
brings up the pop up ).
