Currently, there is no way to organize quizzes into groups under the "Quizzes" tab in Canvas. A lot of the faculty at my school give multiple types of quizzes (e.g. exams, surveys, participation quizzes, etc.). I know that you can add quizzes in weighted groups in the "Assignments Tab" and that you can organize quizzes via the Modules, but a lot of faculty are requesting the ability to separate types of quizzes in the "Quizzes" tab. This would really help separate Classic from New Quizzes as well.
