Don't print All Bank Accounts on combined cashflow recap if only running for one bank

I ran into an issue with the recap page in the cashflow report. The title of the first page reads “combined total for all bank accounts” whether I run the report for one account or several accounts. If I run a cashflow report and include the recap page for one account and the client is aware they have more than one account, they would wonder why the title reads “All” when only one account is displayed.
