If I have someone travelling on a job where they fly out and are due to return say two weeks later but their is a second job that can be done if they stay for a third week.  How can they bill two sepearate expense claims, with the flights on the first job but their hotel and expenses for the third week apply to the second job?  When they try to start the second expense claim it isn't allowed because the dates overlap.  the flight itinerary indicates three weeks in the first claim.
