Hi, clarifying what is meant by V8.0: Multiple destination adresses within one shopping cart

The need is this: an order for 200 units of one same item is made. The client can then choose to ship 100 at one adress, and the 100 remaining at another adress.

Why? Because ordering 200 units would allow him to get a discount. He could do 2 orders, but the he would have to order 2x 100 units and might not enjoy the same discounts if only ordering 100.

Has anyone encountered similar needs and know of a module?
Thanks,
