Import Prodicts by identifier "Supplier Reference" and to be able to edit Supplier Reference in Store Manager

Having the need to import different price lists from different suppliers and not having always the possibility of using the EAN and UPC codes, we need to use a unique alphanumeric field of import. PrestaShop offers the "Supplier Reference" field available but store manager can neither edit and change the field quickly in the table nor in the product. The management of this field is important and even more important is to use it as a unique identifier for the import.
This functionality (editing and import) is present in competing products less efficient compared to yours.
I sincerely hope that this feature is implemented to allow us to make the pro megli store managers who have purchased and the automatic import module.

Thanks in advance
