show balances in each acct when approving invoices

Would it be possible to have a drop down or something to show the balances in each account rather than cumulative? It would be helpful to know if there are funds available in an alternate account (like a money market or savings) or if a dist from a company needs to be done so I can instruct my bookkeeper. Right now, you have to come out of "TO APPROVE" and go to the main page to see all the individual account balances.
