One Order, with Multiple Shipments

Hello,

Is it possible to manage and track multiple shipments for a single order.

For example, if I have a product in stock but another I do not, I would like to be able to fulfill the order by two shipments. This is how Amazon operates.

I thought maybe create multiple status': Ship1, Ship2, Ship3, Fully Shipped. The majority of orders will go straight to fully shipped.

But I can't see a way of controlling which products have been shipped and which have not. I think it is all or nothing.

Is there something I am missing?

Thanks,

Tony
