Linking other manufacturing files during pack and go

I'm sure I'm not alone in this matter so here goes:

I would LOVE to attach my related *.dxf, *.pdf and *.igs files to my Pack and Go at first shot. Without writing a macro is anyone aware of a method to have them come up as linked at P&G time? We distribute these files included to our manufacturer. As you can imagine, doing it after the fact and 'longhand' can present the oppurtunity for errors.

Thanks!
