Handles on points?

Is it within reasion to add handles to points (for roto purposes)? I’m not sure if Motor has this function already or not? These handles would shear the line between two points depending on which direction you push or pull them.

Basicly can you allow motor users to expose hidden rotation points (handles) on a single point?

(i.e.: ctrl + left click drag on a single cusped point)

Thank you,
