Prune the members list of a single user group?

[WATRD]

We have an open enrollment usergroup that we would like to prune/delete the membership from time to time.

Is there a way to do this easily? I am picturing a page with the members of the group listed and a checkbox next to each that says "Remove member from group" That way I could check multiple names and remove them.

Or, do I have to go to each individual member and uncheck their membership one at a time?

Thanks!
