We have a few customers paying larger prepayments, typically equivalent to 6 or more months of subscription.

We still have them on a monthly plan.

The way it works now, the customers CC is still charged monthly even if the customer have unused prepayments/positive balances. I would like that if they have "unused prepayments", the new subscription charge is applied to this prepayment, and no new CC charge is made before the balance is "used".

I guess this is something very similar to the new functionallity around "unused credits".

Are there any way I can achieve what I want? If not, could you consider it as a future request?

Any other which could see the use for this functionality?

Thank you,

Lasse
