Can you create a custom Self-Service Grouping on a Benefits Life Event

Is it possible to create a custom Self-Service Grouping in the Benefits Module on a Life Event? We are testing Redwood Benefits. We have Life Events that are applicable to all three categories - Me, Spouse, and Child. Rather than create three separate Life Events to accommodate the three categories we want to create one custom Self-Service Group, so the Life Event appears in all three drop downs. We are not finding the table where we might create a custom. Self-Service Grouping.
