Different twist angles at root and tip

Dear Jerome:

I am making a set of blades for my wind turbine. Your program looks promising.

My goal is to make a blade that is 3 meters long. It will be 5 degree open at tip and 10 degree at root. Can your program config to do that? I have checked, but it can't. Is it possible that you add in this function?

Thanks in advance for your help.
