I know that in New Quizzes, we can apply a single student's accommodations (extra time or attempts) to all of their Canvas Quizzes; however, some teachers have *many* students in a single class who have the same accommodation (e.g., time-and-a-half), and it can get tedious and repetitive to set the same accommodation for each student individually.
It would be more efficient / convenient to be able to select *multiple* students at the same time for which to set the same accommodation(s). I would imagine this could be accomplished via a column of tick boxes to the left of student names, where you can select multiple students, then click the pencil icon or moderate button to set the same accommodation(s) for all of the selected students.
