Answer 3

Since I don't know if this Question is being look into I figured out a work around to what I'm trying to do.  However it's still something that should be considering.  How to fix the issue: Adding a control point between the center and end points would remove the need for the linear and symmetry option since you could straighten the line out.

As you can see it gives greater flexibility.   The work around I created uses two instances of a plugin unnecessarily.
