Level III Deferral


I have registered for Sep 1, 2023 Level III exam, however due to demanding work schedule and frequent travelling I am thinking of deferring my Level III exam to Feb '24. However, I don’t see any option to defer my current Sep '23 registration to Feb '24!

Can anyone please confirm if Sep '23 to Feb '24 deferral (paid deferral) is possible and if yes how to do that? Thanks in advance.
