When teachers go to My Workspace and create a folder and share it with another teacher, the teachers can add playlists, activities, and quizzes into that shared folder.

From that shared folder, if the playlist or activity is opened, there is an option to assign either the original or a copy.

The PROBLEM is that when the QUIZ is opened, it opens in a "student view" instead of the instructor view and there is NO OPTION to assign it.

Please see the video for an example:
