We are running Zen Cart v1.3.8a/v1.3.8 with Products With Attribute Stock Module. We have thousands of products and many that have multiple attributes (ie. sandal with sizes and colors) and adding the inventory levels per attribute is VERY time consuming.

How do we bulk upload the inventory levels? CSV, QB file, DB, ....? Any help is appreciated. Free goodies to anyone with a solution for us.
