Flexibility for how percentage discounts apply to >1 item

[picocodes]

Would be great to have an option whereby a discount code that is for a percentage discount can be set to apply either only to a single quantity of the most expensive or the cheapest item in the cart/invoice, or to a single quantity of every item in the cart/invoice, rather than apply to all eligible items and entire quantity. That is, if the user is buying item A 3 times in one transaction, the percentage discount can apply only to one quantity of that item, so that if the code is set to be single use or single use per user, the won’t be able to purchase more than 1 quantity of that item on a discounted rate.
