Yes. You can use the clone option to make a copy of an existing customer storefront. For step-by-step instructions, please click here.
Please Note: If you're creating multiple customer storefronts that have the same custom products and departments within them, we suggest creating all of your products and departments first then enable them on the first customer storefront. Next, you'll want to clone the customer storefront. This will make it so your custom products and departments are enabled on all of the cloned customer storefronts. Then if need be, you can adjust it furthermore for each storefront individually. If you add more products and departments after you create the customer storefronts, you can still enable the product and department, but will have to do it for each of your customer storefronts.
Note: This feature is only available for customers subscribed to the online store prior to April 22nd, 2019.
