Customer Delivery Hours and Transportation Module - HELP!

We have the need to specify customer delivery TIMES in addition to the requested delivery date for sales orders. We've been noting delivery hours in print messages but are looking for a way to store these values in a field that populates on the shipment record so they are more visible to the transportation team in JDE.

Has anyone had experience with populating the delivery TIMES on a shipment record based on a default?

Background - We are on 9.0 with a tools release of 9.1.4 and use the Transportation Module for all our outbound and inbound shipments.
