Discount Management - Autoapplied discounts to only apply when corresponding product added to basket

Ability to only populate discounts when corresponding products are added to the basket - We have a discount where the customer receives a free product when they spend over £50 but not all customers want or need this product - the auto discount only allows one requirement (ie over £50 spend) so it populates in the basket for ALL orders and shows on the customers order/invoice even when they did not add this product - this causes confusion and it should only show IF the customer adds the free product. Having two requirements would help with this.
