Problem with discount and shipping

Good morning,

I have a problem with Woocommerce and would like to know if this plugin or its pro version could give me the solution.

The question is: I want to apply a 20% discount on the purchase, also in this store once you exceed 40€ the shipping is free, but if a user exceeds 40€ and uses the discount, so the final price is less than 40€, you lose the free shipping.

I would like to know if there is any possibility of solving this problem, that is to say, that in a purchase over 40€ in which the programmed discount is applied, the free shipping is not lost even if the final value of the purchase is under 40€.

That is to say, that the free shipping only takes into account the value of the purchase BEFORE applying the discount.

Thank u.
