WISH: Copy Paste Weight of SUBD Edges

Hello,
First thank you for the Subd edges control, it is an amazing tool
Using with a lot of fun the % of subedges to create simple Subd Geometries but with a lot of “details” without adding edges.
But is is actually not friendly to use, so my wish would be:
Like a brush of copy paste, you choose a BRUSH icon , using ALT+click on an Edge, you store the value of crease/smooth, the each time you click on a new edge, it applies the value.
The brush ICON could be Duplicate to create easily, a 40% brush or 90%…by default.

Could this type of Brush Icon could be create easily? by myself, of in a future WIP release

Thank you
