Is it possible to update product fields based on the barcode as a key instead of the external external_id?

I get regular price list updates (> 1.000 products) from suppliers with new pricing. So I need to be able to update these prices based on the barcode.

If I need to use the external_id I need to do an export from Odoo and I need to check every product for changes manually OR I need to match all external_ids with the barcodes on the new price list. This is HOURS OF WORK each time there's a new price list.

So it would be much more user friendly if it's possible to update products based on their barcode.

I don't think it's useful to solve this like it's mentioned in this post: https://www.odoo.com/nl_NL/forum/help-1/re-import-or-update-products-from-external-pricelist-file-when-product-barcode-is-defined-288751 since you're always creating new products and none of the statistics will be available anymore.
