Ability to Manually Unsubscribe Contacts

I realize that we shouldn't be able to re-subscribe contacts that have clicked on an unsubscribe link - Only they should be able to re-subscribe themselves.

However, we should be able to manually unsubscribe them.  Currently we can't set "Unsubscribed from all email" to yes if a contact emails us that they want to be unsubscribed or if they unsubscribed through a different CRM software.
