Is it possible to create the opportunity to either enter a shipping weight manually or adjust it at the time an order is released?  As an example, due to pallets being different sizes and weights the auto-calculation of weights based on item weight is never accurate for shipments that have to be palletized.  It would be nice to be able to either overwrite what the system generates OR have pallet weight be an entry field that gets added to the item weight calculation so that accurate weight information can be printed on documents.
