Update products by supplier reference

Hi,

I'm using the latest version of Prestashop Manager 2.17.0 Proffesional. I wonder if its possible to include update by supplier in the import/export products. This is very insteresant in case, for example,when you have 2 o more providers with the same product code or EAN code, and using the automated product import, each one have a different stock quantity (in certain cases 0 vs 199 for example).

I hope you can improve it.

Best Regards,
