When a User Subscribed to One List it Auto Gets Unsubscribe From Another List

Is it possible in PHPList that if a user is Subscribed to say list=3 by subscribe pages then that user is automatically be unsubscriber from say list=2?

The capability to do this is not in phpList. It is possible to go directly into the database and update the list subscriptions, but you need to understand SQL commands to do this.
