How to automatically populate all expense report fields from GetThere Travel Trip Itinerary?

Content (required):

User has booked travel via GetThere, and trip details were brought back to Oracle. However, when we created the expense report from the itinerary in the Trips page, only date and amounts were automatically populated in the expense report. I would expect that for a flight, other attributes would be automatically populated from the itinerary as well, such as Merchant, Flight Class, Departure City, Arrival City. How do we accomplish this?
