UPDATE 2014.5 - Product Lists now supported through the Data Import Tool

Product Lists and their products can now be created/modified/deleted through the Data Import tool.

Creating a Product List: You can create a new ProductList by providing a name for the ProductListName import column. You can also create a new list with a product.

Adding Products to a Product List: You can update an existing list by providing an ID for the ProductListID import column. Since productlist names are not unique, the name of the list cannot be used for updating a product list. You can use a product's ID, ItemNumber, or name to add it to a list. You can add a specific variant of a product by also specifying either the variantInventoryID or the VariantInventoryItemNumber.

Removing Products from a Product List: You can remove products from an existing list by following the same procedure as adding a product, and setting the DeleteProductFromList column to true.
