Hi! My wife manages a shoe eCommerce with a crazy stock. The owner used to use an outdated excel as her stock management, and my wife is updating everything to control it using Woocommerce's stock level. The store has 300 items with around 8 variants (size + color) each. Is there an easy way to update stock information on all those? Currently using native inventory management she has to open item by item and expand each variation. Can she quick edit or something like that with ATUM, either with the free plugin or with a premium one?
