I would like to be able to have a top level BOM with all of the parts listed out for an assembly made up of both parts and sub assemblies and then have the item number remain constant through out the print package.  For instance if I am in a sub assembly I would like all of the parts in that sub assembly keep whatever their item number was from the top level view.  The idea being that if you run across a part with a BOM #1 anywhere in the print set it will be the same part.  I did some poking around google, but I didn't see anything that seemed to be what I was looking for.

Is there anyway to do this?
