Is there a way to define edges with variable mean creases? Well, more like crease values associated with vertices instead of edges, which would make an edge have variable crease values, e.g. if one of its vertex would have 1.0 while the other 0.0 crease values, then the edge would fade away towards the latter.

If such feature does not exist, is there anything that's close to this other than duplicating the given edges and model this manually?
