ShiftPWM support topic. Latest update: Schematics, high power LED's, LED strips

Do you know what I have to change in the library to use it for Duo LED?

For example, if I want to light up LED 1 and 3 in yellow (wiring is RGRGRG) i have to use the following

ShiftPWM.SetRGB(0, 255,255,0);
ShiftPWM.SetRGB(1, 0,255,255);

Is there a way to edit the library so I can use it like this?:
ShiftPWM.SetRGB(0, 255,255);
ShiftPWM.SetRGB(2, 255,255);
