I'm working on a set of schematics where the +24 is blue, and the DC com is blue with a white stripe.  Because the white stripe is a secondary color, on the screen, both wires show up as blue lines, and it's a bit confusing to look at.  Does anyone know of a way to have wires on screen show up with a secondary color?  Sort of like this:

(If you can't see that picture where well, it's a regular blue line, but I put a dashed white line on top of it)

I'm looking for a way to do that automatically though.  I don't want to be overlaying dashed lines on every DC common.

Thanks!
