Compound assignments

Perusall allows instructors to create annotation assignments from multiple sources.

This was mentioned as a key feature by Ana Grinberg at Auburn. It's also highlighted in Cornell's comparison of Hypothesis and Perusall.

Instructors can create an annotation assignment on a video, followed by annotation of a website (static snapshot), followed by annotation of a PDF of an article, all part of one assignment workflow for the student and one gradable artifact for the instructor.
