Post Election Edit Formula not working unless we list specific life event names

Summary: We have a pretty complex set of rules requiring post election edit rules to work with one another that are tied to different plans, plan types. We'd like to avoid having to list out the specific life event name in order for the formula logic to work. It seems the formula requires the life event name because some life events have different coverage eff dates than others. Does anyone have a solid post election edit formula that looks at effective dates and not specific life event names?

Our logic: If employee type A unenrolls in Medical, then they are required to unenroll in STD, LTD and Company Paid Basic Life.
