I have several suppliers that have many locations all over around the country. Sometimes I send them one purchase order and if they don't have all the items available in my city, they will ship the missing ones from another location. But then, instead of having one bank charge for that bill, I will have 2, 3 or more charges that sum the amount on the purchase order and bill. This happens at least twice a week. So, how dow I add multiple bank charges to one bill?
