I have a schematic set created outside SWE.  It includes a printed circuit board with dozens of receptacles for connectors.  The drawing set includes a page where the PCB is represented as a simple rectangle, with the equivalent of orig/dest symbol for each connection around the periphery, like this:

On various other sheets, the actual mating connectors are shown with their wires and a corresponding origin/dest symbol:

I would like to duplicate this using SWE, but I'm not sure what the best approach is.  The more automatic, the better.  I can make an orig/dest connection and then delete the wires, but then there's no easy way to have the matching text on each end.  Could I use a simplified concection label for this?  Is there some other approach I'm not thinking of?
