If you are not posting to these accounts you can set Print Zero Balance Accounts to No (Print > All and Print > Block ) and Include Empty Accounts No (Print > Account Ledgers).
Make sure the Normal Rep of the accounts (nominal) are set to Periodic along with the other accounts on the P&L Statement. When selecting a date range with F11 (Window > Define Columns) set your Begin date and End Date and Respect Normal Rep set this to Yes. This will show balances for the accounts with transaction within the specified date range.
You do not need to add closing entries to your NV2 application databases.
