Edit Item Status on Specific Quantities

Example: If we have 5 of the same HDMI Cable but we only have 2 in stock, we want to be able to select 2 "In Stock" and the other 3 "Ready to Order" (without having to have each item on it's own individual line because it's so difficult to navigate the Item Status page that way). And then if we've ordered 3 and they split up a shipment, we could then change the ones we've received to "Received" and leave the open quantity as "Ordered".
