Adding a feature upgrade to select multiple listings for a promo code to apply within one set-up screen. Currently, there is only the option of applying a promo code to ONE listing or ALL listings with a Catalog or SubCatalog. It takes a lot of time to set up individual promo codes for multiple listings when you don't want a promo code to apply to an entire Catalog/SubCatalog, but more than one listing. Having an option to CTRL to select more than one listing at one time within a Catalog/SubCatalog would save manual work.
