If you execute the .cmd file produced by gsch2pcb, the pin names are
renamed to match the net-list.

I just searched for an example in one of my designs where it did not
match, and have:

# Start of element U18
ChangePinName(U18, 8, Ref B)
ChangePinName(U18, 10, Sense B)
ChangePinName(U18, 9, Out B)
ChangePinName(U18, 5, + In B)
ChangePinName(U18, 6, - In B)
ChangePinName(U18, 14, Ref A)
ChangePinName(U18, 12, Sense A)
ChangePinName(U18, 4, V-)
ChangePinName(U18, 11, V+)
ChangePinName(U18, 13, Out A)
ChangePinName(U18, 3, + In A)
ChangePinName(U18, 2, - In A)


When I hit the short-cut to show the pin-out ("d"), on that chip, I get
the descriptive names assigned to the pins. The on-hover tool-tip still
shows the foot-print assigned name, as does the net-list.

Whether or not you see the pin numbers, of the descriptive names can be
toggled from the View menu. (View->"Enable Pinout shows number").


Perhaps not the most obvious feature in the world?
