Can Termination be Triggered to be Detected one day before the Effective Date?

Summary:

Hi,

I have been struggling to configure a Fast Formula, type "Evaluate Life Event", for the delivered Termination life event to have the life event show up in a detected status the last day the terminated employee is active (the day prior to the current detected status of the life event). I have attempted to use the link below, provided by Oracle but the examples don't provide an understanding of how to use the life event type for my specific case

Does anyone in the community have any experience in creating these formulas and implementing date logic within Fast Formulas for the benefits module?
