We have a number of lessons on our timetable where there is more than one teacher allocated to a set - e.g. the lesson is team taught, one teacher is shadowing the other, they alternate taking the lesson, or use a breakout room.
If one of those teachers is absent, the cover admin needs an easy way to see in Cover Manager that the lesson already has a second teacher timetabled so there is probably no need to allocate a cover teacher (unless they are both absent).
