In Database View it is possible to add multiple instances of the same constituent code to a constituent record by adding additional rows. This is not allowed in Web View. Our organization adds and removes constituent codes to track when that constituent joins and leaves given constituencies (Examples: a student withdraws for a year, then re-enrolls; an employee leaves for two years then rejoins the team).

At the very least it should be possible to add another instance of the same constituent code if the previous instance of that same code has been end-dated.
