Performance Management (OSA)- New supervisor not dynamically updated

PMP Appraisal template is not updating the Appraiser (Supervisor) field when an employee has an organizational movement change (e.g. Promotion/Demotion). The template keeps the same supervisor as when the template was created. New Supervisor will not show as the Appraiser. Is the only option to use the Administrator function through PHAP_ADMIN to manually change?

Thoughts appreciated on a custom solution.
