Import Students Into Classes

As I’m in the process of adding ~500 students into sections with their homeroom teachers I’m starting to ask myself if there isn’t a better way. This year because all our students are new I can import students directly into the class.

Next year as I’m transferring the students, I’m going to have to select each individually to add to the class.

Is there a way that we can import a csv with headers of Username/ClassName to assign that username to that class?
