Procedural guide curves - hair groom


I would like to know how to directly control guide curves of a groom.

I believe it could be something similar to the “simulation” option, but in my case, the guide curves are procedurally animated on CPU. (Imagine some sort of medusa hair, where the motion is blended from different animations, or using some modifiers (sin, cos, etc…))

I would need to retrieve the follicle positions from the skinned mesh somehow, animate the curves and give them to the groom system for interpolation. Is it possible with currently available API?

(if not, any hint of where should I modify the source code for that?)
