How can I get the peak indicators working in a manual map?

I have a Gemini G2V, and I have done a manual map of most of the functions. There is some stuff that I just don’t seem to be able to do, since the DJay Pro software doesn’t seem to support it. I have used the MIDI out feature so that the LEDs on the controller are working. I wondered though, if there is a way to add support for the peak indicators, beside both the deck volume slider, and the deck Gain knob. Thanks in advance.
