link pcb and schematic

Hi All,

I'm using SBP16.5.

Typically at my workplace I'll create a schematic in OrCad CIS and we'll send it out to company X to have a board routed. X then sends the routed board to us for approval. We tell them what we want them to rerout, they send a new board, and it goes back and forth like that until we get a board we can approve. So, my question is......is there an easy way to link the schematic and each new pcb for cross probing? I need to end up linking  the schematic to, say, six boards.......same netlist of course, just different routing. The boards all have unique names. TIA.

Regards,

Bob
