Is it possible to save a partially completed bank statement reconciliation?

Summary: If a bank statement line has not been completely reconciled, we would like to be able to save the partially completed reconciliation to return to it later.

Content (required): We have a situation where there is a large number of system transactions to one bank statement line. It can be difficult and time consuming to identify and check the system transactions that relate to the line. If the reconciliation button is not pressed, the check mark against statement lines and system transaction lines are not retained. This means the reconciliation needs to be completed all at once - is there a way to save the partially completed reconciliation?
