prestashop 1.6 Cart rules - Discount per piece of product

[George Kaliamvakos]

Hello, I am trying to create a cart rule for one specific product and automatically apply a certain discount (amount) on this particular product on the shopping cart. Right now I can only apply the discount once per product no matter how many pieces of the same product are in the shopping cart. The problem is that I want to apply the discount as many times as the pieces of the product, for instance if the discount is 5€, and someone buys 2 pieces of this same product, I want the discount to be 10€ instead of 5€. Is this possible and if yes, how? 

Thank you in advance
