Product Selections let you offer tailored Product catalogs across different sales channels, such as brand sites, regional shops, or brick-and-mortar Stores. Previously, you had to create and adjust each Product Selection and its Product assignments individually, which was time-consuming for large or frequently changing assortments. Now you can bulk manage Product Selections and their Product assignments, including Variant inclusions and exclusions, in a single CSV file. This makes it faster to build new catalogs, update assortments across many Stores, and keep Product Selections in sync with data from external systems.
