Don't want to see System Transactions in Manual Reconciliations page for Dummy Bank Accounts

He have defined a dummy bank account in Fusion and user doesn't want the transactions to be shown in Manual Reconciliation in Cash Management as they cannot reconcile 

1. Can we restrict this bank account to be shown in the list of banks in Manual Reconciliation page

Or

2. Can we restrict the transactions not to be shown under system Transactions. 

If the above is not possible, will there be any issue or impact if we

1. leave those system transactions without reconciling them

Or

2. create a manual bank statement and reconcile them with system transactions

 

Thanks in Advance😊
