We want to be able to have more than one teacher marked for a set for example PE and Sports. Then the additional teachers can see the lesson in their timetable and also be marked as unavailable for Cover.

This is different to associated teachers which does not create a timetable entry for the additional teachers.

At the moment the solution is to a create 'ghost' set for each additional teacher and add the teacher and times (but with no students) to that and repeat for 3 or more - very time consuming and messy.
