How can you create a global net in a Spectre netlist that does not end in !

The model library I have from the foundry has a global signal in the components called PSUB. The foundry says to create a global net PSUB at the begining of the netlist and connect it to ground. The only way to create a global in virtuoso seems to be to give it the ! postscript. When I do this, the names don't match and I still have floating nodes. Is there some way to resolve this besides modifying the whole model library?

    I tried this but the simulator gets an error that I think is caused by the fact that I have not been able to stop it from automatically generating a statement:

     global 0

    So, when I try to include the file with the extra global statement there is an error because you can only have one global statement. I think this would work if I could get it to stop generating the global 0 statement.

     Thanks for your help.
