Edge weight on a modifier

Hi all,

I modeled something flat to which I applied a solidify modifier and then a subsurf modifier,

Is it possible to change the subsurf weight of an edge which links two points of the initial surface to the offseted surface which only exist as a modifier?



Edge Crease via edge menue or directly with shift-E (in edit mode).

Thanks I didn’t know that shorcut, but the issue here is that I can’t select the edge because it’s only generated if I apply the thickness modifier.

Oh yes the new “thickness edges” aren’t selectable… maybe someone could help if you show an image?
