Cash Management - Reconcile a voided payment

Hello

here is my scenario, could you please advice how to handle this - My question is focused primarily on reconciling AP Payments.

Day1 - Received a bank statement for $8500

     Line 1 - Receipts = 500

     Line 2 - Payments = 8000

Day1 - Bank rec team users, go into cash management and reconcile these

    Line1 - Reconciled to multiple receipts

    Line2 - reconciled to multiple payments (example: say 10 payments of $800 each)

** All good so far***

Day1, user has to un reconcile one of the payment, as it has to be voided.

Hence Line2 on the bank statement for 8000 - now shows

          Reconciled amount = 7200 (which is 8000-800) and
