It's great to hear about the change in 2021. We haven't migrated yet but I look forward to playing with it.
Our solution was to edit the signal list to include all the signals we use in our standard with both a regular and POE version for network signals. DANTEP, DANTES, DANTEPP(DANTE PRIMARY POE), ETC.
In the classes I then set our standard colors and a dashed for POE.
For existing lines we are just changing the cable type to say "EXISTING", instead of doing a dotted line.
