MUC Private Messages History

Hi,

As you know it's possible to specify a muc room history which sends the last n messages to the user sent to the room upon joining the room.
Now if User A sends some private messages to User B using the MUC private messages feature (i.e. using this jid: room@conference.example.com/B and the message type "chat") and User B somehow is being disconnected and has to reconnect, there's no history of this conversation.

Is it possible to do that in a similar way?
