[Koha] Can we clear old/paid fines from borrower records?

Dear all We charge overdue fines by the day, which means that someone with 15 items out late, has 15 lines of say 20c each. When we pay them we get 15 more lines of 'Payment - thanks'. It doesn't take long before the balance is off the bottom of the screen, and it becomes difficult to see which amounts are still outstanding. Is there a way to clear or compress old fines, as there is to clear circulation history from borrower records? I would like a way to move the paid amounts to a separate screen (fine log), and keep only unpaid amounts in the screen you see when paying. We are on Koha 3.00.00.107.
