I teach a course that on canvas consists of four merged sections. There are four ways to register for this course (math/CS grad/undergrad) but it's all the same course that meets at the same time in person.  I would like to create an attendance seating chart for the merged class, but as far as I can tell, canvas wants to keep the four sections separate.  The result is that I cannot see the seating chart for the whole class at once, but rather have to go back and forth between the four options in order to figure out who people are.  Is there a way to tell canvas that I want to see a seating chart for the whole class all together?

Thanks.
