Need sticky filtering in SpeedGrader

Hi

We are struggling in one of our bigger courses.

We have multiple TA's (biggest course has around 30 TA's) that do marking for their specific subset of students.

We use Speed Grader because we are using rubrics.

What would be nice is some kind of sticky filtering in Speed Grader, so TA's could set-up just seeing the students they are responsible for.

Am I missing something? 

I there a way to filter in Speed Grader?

thanks
