Reverse polarity of a victor at declaration?

[frdrake]

So I searched but couldn't find this question answered anywhere else.

Is there a way to inverse the victor commands at declaration of the motor? By which I mean as the motors go on there's a possibility that a motor command of 1 makes it go backward when it comes to driving the robot. Am I stuck modifying the motorcommand during processing or is there an overloaded way during declaration to tell the robot that motor is backwards?
