Hi Philip,
What you are trying to do requires bus follows, the way we do bus follows in Acuity with source substitutions is by creating different bus maps and assigning them to the corresponding buses. The way we do bus follows (Auto follows as we call them) is by having panel buttons follow each other across Buses.
Create your primary bus map using MEx PGM A, then create a second bus map and swap MEx PGMA for MEx PGMC (Make sure they land on the same button). This secondary bus map can be applied to any bus, an Entire ME, an Aux bus, or even a key bus of a certain ME. Be sure to apply both Bus maps to their appropriate Buses / ME's
Then go to the autofollow setup menu (Home > Setup > Personaily > Autofollow setup > And choose ME if you want to have ME's follow or choose Buses if you are looking to have an Aux follow an ME.
Lastly in the same menu under config, set AutoFollow Panel to 'ON'. Note the setting in the menu also allowing Custom controls to be allowed in auto follows.
Hopefully this gets you on the right path.
