I have 2 users with different card numbers linked to one credit card account. When I am trying to link my QuickBooks online to the credit card account it asks me to select an account from quickbooks. I selected 1 card to be linked to the main account in the chart of accounts and the 2nd card is linked to a subaccount under the same chart of account. 

I get a message "The account, Chase Ink, has a subaccount that is already connected to an account at one of your banks."

How do I create this?
