All my products are sold either individually or in boxes (the quantity depends on the product). In order to simplify our management in Odoo, I would like to import all my packaging with the quantity contained and the barcode of this carton/packaging.

Unfortunately, I have a problem because many products have the same packaging but with different barcodes (e.g. "Box of 3 packs", "Box of 4 packs", ...). My import does not work because they have the same name (but different barcodes). Every time I import, everything gets overwritten and only the last lines are imported. Odoo tells me this:

Found multiple matches for field 'Product Packages' (13 matches) at 19 different rows:

What can I do in this case?
