Can I prevent the sale of sold-out items through the Virtual Terminal?

I have an online store and also sell through the Virtual Terminal. Why if my stock is sold out, does it still allow sale through the Terminal? It correctly won't let me buy online, however if I add it to a Virtual Terminal sale, it correctly is listed as "Sold out," but I can still list it on a bill of sale and accept payment through the "Other payment" choice.

I have limited the Virtual Terminal to Other payments, because we us the Virtual Terminal to record sent it paper sales with checks. If there is no inventory, why does it still allow me to go through recording such a sale? Can I turn that feature off?

Even if I mark the item as "Unavailable," I still can mark a purchase of it in the Virtual Terminal. The problem is my assistant may not always see the marking of the item as "Out of stock." He appears to have made that kind of mistake before, although I am not sure this is the reason that out of stock items still got purchased in the past.
