At Productsup, we are continuously working to offer you the best P2C experience. See the updates and new features we released to the platform in January 2024.
If you have more than one main data source in a site and need to import your products in a specific order, you can now change the import order with the drag-and-drop option. It isn't merely a visual change. This improvement impacts the order of the product import, regardless of whether the parallel download is active or not.

See Add a main data source to import your products for more information.
