unsubscribe link?

using s2 v9.2 on WP 3.8.1

I’ve tried using the shortcode and the widget to display a link on the front end of my site for folks to unsubscribe. the only thing that ever appears is a link to the subscriptions page on the back end, where I do not want to send my users.

Is there any way to create a link that will globally unsubscribe a user, or even better, a link to unsubscribe them from a particular list, if they are subscribed?
