Hello ! 

I'm a Teacher's Aid for a fairly large class (510 students). the students need to pair up and write a final assignment together, which they will be uploading through Canvas. rather than manually inputting the grades on the assignment of each student, we are trying to create two-person groups (255 in total) to eliminate the redundancy of grading each student. due to the Canvas group number limitation, we are unable to add enough groups to represent our class size. 

any thoughts on how to add enough groups to get to 255? we've attempted creating two group sets - but ran into an obstacle when it came to attaching both groupsets to the same assignment. any thoughts would be greatly appreciated!
