If you go through the "Upload to multiple accounts" option for CSV/PDF import and choose to create a new account on the 'Review Accounts' step, a red error notification will show up on the last step and the transactions associated with that account will fail to insert. Note: The account does get created, and if you exist the import flow to view the Accounts page, you will see the new account there. BUT, even though it does seem to be create the account during the process, if you click 'Back' in the import process to return to the 'Review Accounts' step, that account still doesn't show up in the dropdown.
