It would be great to be able to have the system auto add discounts that apply to a customer when an employee updates an order with adding products. We have wholesale customers that get product discounts, and when creating an order either on the frontend or via the admin, the discounts are automatically added when an item is added. However, a lot of our customers add to their order after it is placed and we have to manually add the discount as an "other item" and manually calculate it. Can there be a button to auto apply discounts when updating an order? Like there is for recalculate shipping and taxes?
