Possible to reverse an extension request??

Hey guys, as the title says, I recently submitted an extension req for an assignment as my partner is moving interstate this week and i’m starting a new job. Also just uni stress yk. But I have finally been able to stop procrastinating and I think I can complete it within the deadline, so I emailed my unit coordinator about reversing the extension so I can save it for another assignment.

Just wondering if anyone has done this before and whether it’s possible? Anyways feel free to share thanks guys
