I think its about SPICE netlist depending on pinseq, and pinseq depends on having a pin, or does it?

Could you make a FET source terminal be a pin with name S and pinseq=3 and somehow have
a pinseq=4 related to the substrate without having  another pin?  He doesn't want to lose substrate in the netlist,
just tie it to S for this particular "part" or transistor layout.
