Customizable Sales Process

We only know our final pallet designation at the end of the sales process, since we transfer to dispatch from production for a large majority of our orders. The current sales process, specifically the packing process, where one would print the packing slip does not allow for us to add any unique fields, which we require in agreement with our customers. 

So I would say this post is a Feature Request for a customizable sales process. We need to be able to actually have additional fields per line item on the order.
