Hi there,

It's something you can do but it will modify the entire behavior of the coupon and discount calculation so I'm not sure that it's what you want.
You should try to edit your coupon and set different characteristics in order to get the value you want. for example set it to 20.01% so if you have a product costing 99.99€ the coupon amount will be 20€.
