Token/Credit Support

Does squarespace support a model like audible, where a client can purchase Credits or Tokens on a subscription that can be later used as purchase entitlements?

I could easily see a scenario where a Subscription issues out a gift-card every month, but I am looking for a way to relate a Stripe Inventory volume entitlement defined in a Subscription Product back to the actual SquareSpace CMS/Order system.

Note: I am aware of how to implement this in Stripe against the Rest API. Just curious if this is a custom integration for squarespace end-to-end, or if there is some rough support, either in the middleware or template UI.

Thanks!
