Crease setting for differents subd

I would like to have in the same project some sub-ds (with crease and not crease edges inside) showed simple (creases) and some others rounded (not creases). It’s possible in some way?
thanks, Roy

Yes, but if you actually want one SubD to be displayed flat and another one smooth at the same time then that would be something I’d also likt to know how it’s done? It was possible in T-Splines.
