add a filter to Trial by date report

What specific challenge or problem does this idea solve?

I would like to be able to see which teachers convert the most trial students. Right now I have to figure it out manually

How should this work?

add a drop down like the student class changes report

Who will benefit (Admins, Staff, Students)?

This would benefit the staff because it would eliminate the time to do the math conversion manually

How will this change impact your daily tasks or overall experience?

It would make a 1 hour task a 5 minute task.
