Only seeing my students in the gradebook

[a101853]

In my course there are multiple instructors, I know how to show only my students in the gradebook, but how can I go from one of my students to the next using the speedgrader? I can see my students now in gradebook and when I go to speedgrader for my first student that is great, but then when I move to the next student, that student is not mine. How can I only see my own students to grade?

Thanks,
