Correct Large Angular Variation Option

Hello, 

I have a CNC machine with some limits on C axis. When I use "Curve Machining", machine has out of limit on C axis and I use the option "Correct Large Angular Variation". Machine is doing correct motions but I want to chance the location of this correction motion.

When retract from the axial motions, machine should correct the C axis in this time. Not when it removes the material. 

How can I do that?

And what is the first and last axial motions? (Please check from pictures).
