In Wallet you can set the type of account (for example, overdraft). You can then set an overdraft limit and have your actual balance displayed in the Wallet.
Here is how to do it:
1. Select your account
2. select account type > Account with overdraft
3. Set your limit
4. Display balance options > you can show an actual balance on your account without an available overdraft limit OR your available balance on your account that includes an overdraft limit
5. Then set your payment due date so that you are reminded before the extended overdraft fee takes your account deeper into the red.
