looking through this issue I realized you could get a nice solution by simply adding a new tab for creditcards with the same exact content of Bank Accounts thus having the chance to import CSV statement files, but not adding to the final “Cash at bank” table in the Summary tab.
This because creditcards get deducted in the bank statement monthly automatically and if we simply use the CC stamenets as Bank accounts the numbers of the Cash at bank is wrong (you would have double deduction from the CC accounts and the deduction in the main bank accounts.
I would use the same for Cash Accounts but now they do not allow for automatic statement import.
This way you could also go through the CC statement and be able to sort the billable expenses and add them to the proper tab.
Hope this is clear and can be easily implemented.
