Is it possible to add free days to an active subscription on Stripe?
I'd like to do it in order to create a referral program: when a user refers someone, he gets 10 free days.
I think a good way to do it would be to update the current_period_end var, but I can't find how to do it in the doc.
For example:
- Bob is subscribed and will be charged on the 15th of this month
- He refers Alice
- He gets 10 free days on his account, and his next billing date is now on the 25th

I believe the closest you could do would be apply some sort of credit to her account, so instead of 10 free days, it's earn (33% of monthly fee) per referral.
