chnconvexhull has a limit of 65535 values

chnconvexhull has a limit of 65535 values, can this be increased, I'm still using 11.1 but I could load a later version if this limatation is removed

Is the quickest solution partitioning in 65k chunks form into mini hulls, then making a final convex hull from the mini hulls?

Thanks
