	There isn't form to swap pin labes easely/automaticaly.
	I think that you need to design 2 or more symbols like 9572X-1.sym 9572X-2.sym ... each one with diferent labels tothe pins.
	Usualy we write all the possible function to each pin label like in PIC microcontrolers where you find:
	pin4's label=OSCIN/OSC1/RB3

	But if you are saying about slots like a NANDs ports chip, please read about the symbols slots attributes in docs.
