dynamic store with one-of-a-kind items inventory

[rjspomer]

I sell products that I make. These are made up in advance and a inventory is kept. Sometimes an order that comes in depletes the inventory and it is shown in red as a "made to order" item after placed into the cart.

All works great but I do have a few products that are made from limited material therefore can not be a made to order.

How can I make just those show as "out of stock"

Thanks

I guess the setting are all set globally and an individual product item can not be set as if out of stock can't add and another item set that it can be added if stock is depleted.

Thanks
