Two SUBD or Polysurface in one oparation TANGENT fillet?

is there a way ? easy and in one oparation two subd or two joined polysurface, or one subd with one polysurface TANGENT fillet .

thanks…

Have you tried SubD Fusion in Grasshopper?

I like the Fuse component and look forward to improvements as well as a command version some day but I would recommend Bridge here to blend between two SubDs. You just need the same number of faces selected on both across from one another.
