I added an additional column in the database for product attribute product codes. I called it attribute_skus. I have not yet figured out how to make this editable in admin, but it is pretty easy to add the model #'s in PHPmyAdmin. I was able to get the model #'s to display in the same table in admin though so that I am able to verify I added them to the correct variant. If you would like this code I can provide it.
I have not decided if I will go any further with this as my need has already been fulfilled. I just need to be able to import and export inventory using my company's inventory program. I would imagine one could put this info on invoices and shopping cart pages as well pretty easily.
