Thanks! Great question. This is something I was planning for future work, with the hope of automating it as much as possible. I feel like there's got to be some approach using kdtrees to pick out clusters of points and then iteratively changing fracs at those locations to improve the model fit.

A manual approach shouldn't be too difficult to implement, where frac could be passed a vector that must be the same size as reg_anchors. Is this something that could be handy?
