I have a device with 160 pins. The footprint has 4 holes which I want to change to 4 through hole pads (not connected). Can I do that without having to manually reconnect the 160 pins to the pads? Problem: when I try to add delete the hole and add a pad in the package (footprint), I get an error that the package is already in use and that I cannot add the pad. Thanks, Kam
