Subscriptions without Deliveries

By default a subscription app thinks that every order is a delivery. We use subify in a slightly different way, where our customers subscribe and receive a delivery seasonally. It's kind of like spreading the payments over 12 months, but they get other digital benefits too.

It would be cool if add a 'membership' feature, that we could add set specific delivery periods to. There is another service that does this, but they don't play nice with Shopify.
