CSM power per mesh

Hello all,
I would like to know is there is a way to control the cascade shadow power from the directionnal light for a specific mesh.
The light setup is simple : directionnal light and skylight. By decreasing the skylight intensity, I get what I’m looking for on shadows : shadow are darker. I’d like to get the same result on shadows, while keeping the skylight!
Since my purpose is for specific actor, I can’t do it with color grading tools from PPV.

In my screenshot, I did a quick layer blending in PS to illustrate what I’m looking for to do.

Thanks for your advices!

Nope, there is no way to do that.
