Blending Colors

Hello!

I am trying to archive a painted look on my Object in Substance Painter.

And i am searching for something like a blending brush as you would know it in photoshop.

I know there is the smudge brush but it just drags the colors around and i dont get the result i want.

Also there is the flow option but the effect is so minnimal that i also can not work with that.

I also attached an image where you can see what i want to archive.
