Administrator Add to Registration is not the registrant's manage page

In GiveCampus Events, available controls depend on your permissions and the interface used by your institution.

The administrator registration detail exposes Add to Registration for authorized users when the registration is not marked not-attending. The registrant's My Registration page instead shows existing guests, activities and add-ons; the guest-edit setting controls editing existing guest information there. Do not find an administrator-only button or promise that enabling guest edits adds the same capability.

Have the organizer use the authorized existing-registration addition workflow when appropriate. If the registrant already created a second registration as a workaround, reconcile both registrations and associated tickets/payments before deleting or refunding anything; a second registration is not a safe universal way to add a spouse.
