Choose best coupon

Good morning, I’m using this plugin to create a coupon that automatically applies giving 5% discount for orders over 100 euros. The system works correctly, the problem is that the coupon must not be added to other coupons, but at the same time there are other coupons that offer better discounts. I would need the automatic 100 euro coupon to apply, but if a coupon offering a better discount is applied the system should cancel the 5% one and activate the one set by the user. it’s possible? It would also be okay to remove the 5% coupon for any coupons manually entered by the user.

Thank you
