Change single element of a paid invoice (product/service) without deleting rest of the row

How can I change one element (product/service) of a paid/closed invoice, without zeroe-ing out the rest of the row? Today, I changed the product/service field of an old/paid invoice from one thing to another in order to make my year-end reporting more accurate. Doing that erased the description, quantity, rate, and amount. When I re-entered those fields (the final amount due was the same as before as the prices had not changed), the invoice showed that there was a balance due.
