is there a way to email all students who have not submitted an assignment

Is there a way to email "all students who have not submitted an assignment"? Obviously I can email students one by one, but I'm wondering whether there is a way to press a button that will send my message to everyone who fits that description.

never mind! I just figured it out. Go to the grade book, click on the three little dots beside the title of each assignment.
