I'm happy to assist you with adding more than one account for the same bank.
For this to happen, we can add sub-accounts to have more than one credit card linked to the same bank. Let's get this setup and get you back to business.
Click Settings, then Chart of Accounts.
Select New, on the top right-hand corner of the page.
Choose the account type.
Once all the information is complete, click Is sub-account and pick which parent account that it's associated too.
After all the information's complete, hit Save and Close.
