Is there a way to create a footprint with multiple pads connected to a single pin on the part's schematic symbol? As an example, I have a transistor in an SOT223 package, where both the center pin on one edge and the heat sink tab are connected to the collector. I don't want to have two collector pins on the schematic symbol, but I would like to have the flexibility to use either of the available collector connections when routing. Assume the collector is pin 2 on the schematic symbol, it seems that I would have to create a footprint with two pads assigned to pin 2, which PCB123 doesn't allow. Do you know a way around this restriction?
