Call Forwarding based on Status (available, busy, do not disturb, etc)

If a user is in an appointment, away for an extended period, or on lunch, it would be helpful to forward the calls to a receptionist. Currently the call forwarding feature can only be enabled during specific times. It would be helpful to allow the user to enable call forwarding by changing their status to "do not disturb" or adding a new "call forwarding" status. That way it can be easily enabled when they know they will be away.
