Thanks for the suggestion, and I can see how this would be useful.
This is essentially allocating stock to an order’s delivery earlier in the process. I’m sure we can look to implement this, but is certainly a substantial change behind the scenes (for example, not all orders would have their delivery scheduled at this point, but that would be needed for this to work as technically stock is allocated to a delivery, not an order).
I’m linking this with Improved management of pre-orders and reservations as there could be some overlap here.
If anyone else would like to see this, please can you give this a vote
