When I assign a cable to a wire it designates it with "W" and a number. I found the formula for setting the cable marks and its setup as:
CABLE_ROOT + CABLE_ORDERNO
I know i can just change this formula to put any letter I want in replacement of the root. My question is though where can I change the default value of "CABLE_ROOT". Like components, I can go to Library/Cusomization/Component classification, and I can set all the default designator root values of components based on their class. Is there anywhere like this that I can change the root value for cables?
