I don't think you can move the dates around once you have rented. You may be able to add a day on for cash through Disney though. Or maybe even find someone trying to rent a small amount of points and you can add in a rental day.

If all you want to do is add on an additional night it is just easier to book a separate reservation. Inventory is limited and you don't want to lose what you already have.
