Red tally on ME1 and green tally on ME2

[nv1170]

Is it possible to setup two different buses in the Config- Bus options section to be named ME1 and ME2 (or whatever the case may be)? What I'm looking to do, on my BM ATEM, is create essentially two "Programs". Each of my cams will be called from two different MEs but would like to show when a cam is on either ME by making it tally the correct color accordingly. In other words, if cam 1 is cut on ME1 on air, it would go red but when it is cut on ME2, to screens, it would light green. If both MEs cut to that cam then it would turn yellow-ish. Anyway, that's what I'm hoping to accomplish.
