Packaging Hierarchy in a Sales Order

Summary:

We are trying to create a Sales Order for the Finished goods that has a packaging Hierarchy associated with it as shown below:

for the same we have set up standard UOM Conversion as well as defined packing units using Manage Default Packing Configuration.

How to associate the Packaging Hierarchy during Pack operation for shipping the Finished Goods against the Sales Order.

For ex: lets say we we have created Sales order of 100 qty. So the requirement is such that, on shipping the Goods, the system should show that the finished goods is packed with 1 Pallet which contains 5 Cases which in turn contains 4 Packs each which in turn contains 5 units of Finished Goods each (i.e. as per the packaging hierarchy set)
