Script to relocate the menu-bar on dual monitors set-up

Is there a script that could be written to achieve this: In System Preferences/Displays... is it possible to relocate the menu bar ...via a script? My set-up is one monitor and a Cintiq. I either work only with the Cintiq, or I work with my 28" monitor several times a day. I always need to go to do this manually. I really wish there was a script that can do this. I tried Automator, but it's not recording the action. :(
