I have a Bank of America card, where the payments are in one account ("Corp" account) and the charges in the other.  Because of this, there are two feeds to capture all card transactions.  In Banking, I have "credit card charges" and "credit card payments".  I have these feeding 2 general ledger accounts, with the same names (BofA charges and BofA payments).  In the chart of accounts, I created a parent credit card account and made the payment and charges sub accounts of the parent.  This enables me to reconcile the parent account in the reconciliation function because you only get one combined monthly statement.  Worked fine and I didn't have to do any song and dance with the bank feeds.
