Recommended Packaging can assign multiple packages to an order, but it does not show which items have been allocated to each package. Add item-to-box allocation details so packers can see which SKUs or quantities should go into each recommended box, either on the order, packing summary, or packing slip.

Example:

Box 1: X-Large contains items A and B

Box 2: Medium+H contains item C

This would help customers using Recommended Packaging for multi-box orders confirm how the algorithm expects the order to be packed.
