Allow templates to display info of contained items from a pallet during a blind receive.

When doing a blind receive through FLOW WMS, Magaya is not able to see the information of items inside of a container/pallet. Some customers would like to display this on their labels before the blind receive is submitted. This works with regular warehouse receipts, but not through FLOW WMS during a blind receive. This is because items in a blind receive still don't exist in Magaya until the warehouse receipt is created.
