Alongside lots of physical products, our site sells a handful of "digital" products - such as a membership product and downloadable content files. We currently assign these products to a "digital" warehouse but the orders need manually marking as Despatched every so often, which triggers despatch notification emails to be sent to customers, which is weird. It would be great to have a Digital flag on products, which if ticked would mean Storefeeder essentially does nothing with that SKU, and just assumes it has been fulfilled immediately by the storefront.
