Hole Series

I have Assy1, which is made from Part1 and Assy2.  Iwant touse hole series to put some holes through Part1 into Assy2,but theholes in Assy2 have to live in Assy2 only and not live inthe pieceparts of Assy2.  Is there any way of doing this usingholeseries or do I have to put the holes into Part1 andAssy2individually and not in Assy1.

Thanks
