Capturing Penalty Amount in Service Receipts

In service contracts, if the contractor is levied any penalty for non conformance, there is no provision in the Receipt screen in which we have certify only the quantity. The penalties should be captured in the Receipts screen & automatically populated in the invoice screen. Currently there is no such provision in the Receipts screen and the penalty is added manually in the invoice screen as a line item.

Is there any better solution to address this issue ?
