While there is no function for this directly on the Funds In screen, it is fast and easy to do from there.  Simply enter an 'I' for Inquiry in the Proc Code field of any share or share draft account and enter.  Then select F17-OTB/Cards, and lastly F13-Reg E Settings.  From this screen (Overdraft Service for ATM & Everyday Debit Card Transactions) the teller can select whether to opt the member in or out, and can even make the individual account exclusions from this screen.  Use F10-Save/Done to complete the update, and cancel back to the funds in screen to continue with the transaction.
