Don't know of any special "step", but when I need to "expand the intro space" I choose red "REGION" ( the green or red button to the right over grid ) and then put the cursor on track 1 at zero and press and drag down to track 24 and while holding down left mouse button, drag to end of project with mouse and / or use the Jog Wheel ( faster ... ) Every track should be black. Then just grab anywhere with mouse and drag to the right as long as you need.
Note : Any "Automix" settings do not follow the move / drag to the right ....
