does anybody know how I can have a sales discount applied to the item itself as opposed to being added as a line item on the order? this makes determining our gross margin very challenging because we have hundreds of thousands of dollars in a bucket (sales discounts) that aren't being directly attributed to a particular class and product. This can't be done at the header level for the entire transaction because we may have only certain items that qualify for discount (for instance, 20% off shirts and the order includes two shirts and two pairs of pants).
