Benefits coverage end dates for dependents

Hi,

I have a requirement-

dependent coverage end date for child-

when child age >= 26, then child out age event should trigger on the birth date and coverage end date should be the end of the birth month which is end of the month.

similarly for Spouse when relationship divorce is added on the day the coverage end date should be the same day.

The configuration exists in the system:

Program enrollment requirements/Dependent coverage/Plan types -->

dependent coverage start date code- As of event

coverage end date - one day before event

checked derivable factors apply (derived factors- age >26 )
