Adjusting Center of Gravity

Fellow aviators,Given an airplane that shows its center of gravity indicator outside of its weight and balance envelope, is there a way to adjust either the .air file or the configuration file to make the center of gravity be within the W&B envelope? The airplane is the POSKY CRJ7. Great looking airplane, but its center of gravity indicator is on the nose, outside of the W&B envelope. Yes, I've posted in the POSKY forum, and they promptly replied that that the indicator "is messed up. If you have full passengers and a decent amount of cargo, your actual cog is fine, even though graphically it shows it off."Since I don't necessarily want to have full aircraft all the time, I would like to learn how to adjust this. This isn't a criticism against POSKY, they gave us a very good looking bird, for free. Any clues?Best regards,David Vega
