Number of uses until amount is finished

Hi, how do I set a coupon so that it can be used several times, until the value is redeemed?

E.g. a client has a coupon for €40 but spends €25 in my shop
he pays with the coupon, the remaining €15 is saved
when the remaining €15 is spent, the coupon is depublished

Is this possible?

hello, this feature happens with function type of gift certificate, not coupon.
