737-800/900 Pushback in FS9/FS2004

Is it possible to utilize a pushback in the PMDG 737-800/900 running under Flight Simulator 9/2004. It appears this is only available in FSX but I am not entirely sure. However, I have exhausted my efforts to get a pushback in the PMDG 737-800/900 from a cold and dark cockpit after I have the system setup from the overhead panel and the FMC.

Thanks
