How to reverse a pay run without submitting it to the ATO

Hi, I'm facing an issue with reversing a pay run in MYOB without submitting it to the ATO.

I recently switched to MYOB Business and migrated data from my previous account, which is no longer accessible. Since the original pay runs from the old account weren't submitted to the ATO (and can't be resubmitted from the new account), I posted an identical unscheduled pay run and reported it to the ATO. Now, my MYOB shows two duplicate pay runs. I need to reverse the duplicate but ensure it isn't submitted to the ATO.
