Parent categories are selected for you, and conflicts get flagged. Add products to one or more categories in a single pass. By default this adds to their current categories instead of replacing them, so nothing you already set up gets lost. Use this to organize new products or build out a category as your catalog grows. ## Assign products to categories Bulk editing, Assign to Categories across many products at once in WISEPIM Bulk editing, Assign to Categories across many products at once in WISEPIM Check the products you want to categorize.
