run a simple report of student that DID NOT submit assignment?

hi, running moodle 2.5.1, new to 2.x version.

i have an assignment for student to simply upload an assignment, its not graded, etc..

id like to run a simple report if i can to see who didnt submit anything...

i know i can look at the submissions, and click on a top header column and see the unsubmitted that way.. .but tis there some sort of report i can run to see the list/names easily...?

thanks moodlers.
