General ACCAChange Exam Centre Under the online late exam entry process possible?

I have already registered to sit F5 and F6. However I can no longer sit the exams at the exam centre that I selected as I need to be overseas during the exam period.

Under the online late exam entry process is it possible to change the exam centre?

If it is not possible to change the exam centre can I register for F7 under the late entry process at a different exam centre?

thanks
