Add the option to add a "Date To" to existing constituent code instead of adding the "Past..." constituent code. I don't use "Past". I use Date From and Date To because my families can come in and out several times over the course of several years. Also, a family may pull one child out and still have one or more child enrolled. WH adds the "Past constituent" code on to an existing record making it look like they are current and past at the same time.
With a student WH only adds "Past" to the Education and not to the constituent code in Bio 2.
Students aren't my main concern until they graduate, but I do solicit their parents and grandparents as well as keep track of relationships.
