Hi Bravlin, someday perhaps I'll be able to focus on more surface control point editing functionality. It hasn't been a focus area so far because of its limited use in CAD object structure as I described and because there are many polygon modeling programs that already focus very much on that type of modeling.

I recommend using a polygon modeling program if you want to do that style of modeling though, not MoI. It is not currently a very developed or targeted area in MoI.
