We have the ability to import and or update the product catalog via CSV currently, but I would like to add the ability to match products solely on 'part number' instead of 'model'. My use case currently is for the brand C2G which previously had model numbers with a 5-digit code '12345' for the model. Our whole database is setup that way for that manufacturer. They recently added 'cg' in front of their part numbers, so the model is now 'CG12345' and that's how they reference it in price lists. I have made the 'part number' in the updated format and I need to match it based on just that. The CSV import will not allow me to run it without a 'model' present.
