Website credit instead of payout

I'd love the option for affiliates to select website credit – applied to Fluent Cart purchases - instead of cash payout. So for example, if they sign up 10 friends who pay (or possibly just sign up for free trial), they get X amount of credit applied to their account (amounting to free subscriptions). They could also have option to convert that to cash payout later. Is this possible please? It would encourage people to share the link with a few friends – they might not become full affiliates and start an affiliate business but they could get some free access to paid things on the website. I think these small scale affiliates could be really important, particularly if their affiliate link was automatically provided to them after they paid
