Add cost itemization details to contract

Hi, when I add additional costs to the Cost tab on an event, it shows me a clear itemization that includes the quantity, hours, rate and total for each charge. However, when generating the contract, almost all of this important detail is lost. The contract only shows the total cost for each line item with no description about the number of staff, number of hours or rate of pay. I end up having to send a separate email to the group requester explaining the charges.
