Maintain Parent connection in Engage when Students are unenrolled in Desktop

Currently when a Desktop + Engagement user unenrolls a student, the parents are disconnected.
This leads to the customer not being able to send Engagement communication to inactive parents/students, even though Procare Online functionality exists to send Engagement communication to inactive parents/students.
Request is keep the parent connection so that users can continue to send engagement messaging to inactive families if they choose to use that functionality.
