Why can't this be done? It's easier for me to split orders first, then combine later if two items in an order happen to be ready to ship at the same time.
This leads to me doing a lot of manual ship status updates, which are annoying and inefficient.
Thanks
This feature is now available!
You can now split an order (or split the quantity on an order) more than once. You can also combine orders after you split them. Or combine more than once. - Hooray!
