CC teachers or staff on emails sent to students

I would love to have the ability to blind cc teachers on emails sent to a class or groups of students from both the class page and the student list.

Tuesday, September 6, 7:15-8:30
Saturday, September 10, 10:00-10:45
Wednesday, September 14, 5:00-5:3)
Saturday, September 17, 10:00-12:00

Etc, etc.

Shutterfly has something similar in their group pages that works really well. I am sure you could do it better.
