Can I submit the payment order in Central Fee Payment and instruct someone else to make the actual bank transfer?

Yes. As long as the payer quotes the payment reference in the bank transfer, it is irrelevant who submits the payment order. However, payment confirmation will only be issued to the online user account of the person submitting the order.
