Transform Reward Points Into Gift Certificate

I don't want to let customers use the reward points 1 by 1 on payment page.

I prefer to let them transform the points into a gift certificate after a certain amount is reached.

(for example, when they have reached 200 points, they can transform them into a 20.00 certificate).

I cannot find any way to do it, even on marketplace.

Is there an existing solution or should it be developped ?

WE do not know ready to use solutions with such a feature. Looks like ti should be developed from scratch
