Import Product Quanities

I hope this is the correct section. Is it possible to import just new product quantities and not add new products. I ask this because I do not carry my supplier’s full catalog and do not want the import to add these products while updating quantities.

I did a test and the products I do not carry were added along with the new quantities. Is my only option to remove these products prior to the import?

Or give them a status of D or H (disabled or hidden).

The difference is that a hidden page can still be accessed directly while a disabled page cannot.
