Useful if you get hung up on a long entry and need to move on, or if you are invoicing the customer in real-time so that you can keep updating it (without risking it times out and you lose the entry). As requested by a Brent Remyn.

This would be a very useful feature to have. I often have invoices I start and want to have in draft until additional items are added. When you have to keep reversing, it makes a mess in the AR list.
