This is very useful for classes that have different sections but overall are treated as a single class grade-wise.
For example, a phyiscs class will have you sign up for separate lecture, lab, and discussions, each with their own time/assignments/locations/numbered + lettered sections.
This way, you can assign a lab report to the lab section but have it linked to, say, the lecture section so that its grade will still be factored into the overall grade calculations.
