Anyone know if there is a way to change the default "allocation" of inventory to orders? If I have 30 of something in stock, and I have a single order come along which wants 100 of those things, I do not want that single order to "reserve" the 30 items, causing any following onesy-twosy orders be be on backorder. Instead, I'd rather then big order be "on backorder" and any subsequent onesy-twosy's be able to whittle at the 30 remaining in stock.
