Create address book group from email recipients?

[jdsam]

I'm in college and get a lot of emails from a lot of different groups and I often have reason to save them as a group in address book, but I usually stop once I realize that I need to add each of the people to my address book one by one, and then add them all to a group as I go.

Is there a way to streamline this? In an ideal world I would like to be able to create a new group in address book and just copy/click and drag all the address from the email to the group. But, like I said before the biggest issue right now is having to add each person to address book one at a time, simplifying that process alone would be a huge help. Any suggestions, is what I'm thinking of even possible?

Thanks,
