Create tag to indicate if stock is available

[steven]

This, I think, would be a really simple add.  There needs a to be a way to quickly glance at an order (without selecting it) to see if there is stock available for the order or not.  

Right now, I have to go through each order, one by one, to see if there is any stock available and sort the orders accordingly. It would be so much faster if I could just create a tag that applies to every order to check the inventory levels. That way I can quickly sort between orders that have stock and orders that don't have stock.
