Remove Contact Without Needing to Replace With Different Contact

Once a contact is added to a role in an event, there isn't a way to remove the contact unless you replace it with a different contact. Sometimes an instructor is unassigned from a class, and another instructor isn't immediately assigned to the class. Until another instructor is assigned to the class, it looks as if the previous instructor is still teaching the course. This can be an issue when binding courses, as the course could be bound with courses that it shouldn't be bound with based on the contact role. It could also be misleading in any event searches and reports that include the course and instructor.
