When you’re looking at a bank account view in QuickFile there’s a button at the top to add a new transaction. You can do it from either end, create a “money out” transaction on the current account and tag as a transfer to directors loan, or create “money in” on the DL and tag as a transfer from the current account.
For bulk recoding see this thread - if that tool won’t handle your case then you’ll have to ask QuickFile staff to help you.
