A "Print" Track and the end

I am watching a Youtube video by Sweetwater of the entire mix process being done (In Pro Tools) of the Counting Crows... There engineer set up a "Master" fader aux bus - which is sent to and followed finally  by a "Print" stereo track where the entire mix is then recorded to. Is there a way (I have X1) to put a track at the end - I don't see where in Sonar that option is offered. The only drop down option in the bus section is to add another stero bus, but not any tracks?? 
 
thanks ! 

Thanks ---- it was a cool process to watch. While recording the mix to that track, they tweak a small section in the mix, and then just punched recorded it over that last part, and so did a quick on the fly edit of the final tracking. The other issue that prevents this in Soanr - we cannot route a Master bus to a new track for recording of the whole mix!!!

Wow thanks.... could you give a little more detail...when you refer to "bounce the master bus output to a track" -the steps of doing that?   thanks!   one other ? on this.
 
Is it right to assume that then you take that final mix track you like and "export" that one alone down to wav or disc.
