Hi Moi3dFan,

re:

Sorry no there isn't a way to do either of these things currently.

Surface control point manipulation generally works better with sub-d surfaces instead of NURBS surfaces.

You may want to use a sub-d modeling program to do surface point manipulation type work and then convert the sub-d surface into MoI using SubD > Create > "From file".
