Discount for purchasing more than 1 product

I am using Hika Shop Business and I need to do a discount of products based on a category. For example, I have a category for "Buy 2 suits for $150" and I want the customer to be able to buy 1 single breasted suit and 1 double breasted suit and get the discount. All the suits are the same price.

Is this possible?

What you could try to do is to have a coupon with a minimum quantity of 2 and select the category of products you want and activate the option "Coupon percentage applies to product only" and the option "Auto load in cart if possible".
