Pen tilt for natural "pencil shading": Reverse scatter dynamics?

I want to be able to tilt my brush to get a broader scatter effect. This would allow me to hold my pen upright to use a pencil brush with a thin, sharp line; and then tilt the pen for a broader, softer, more scattered line. This would simulate tilting a pencil in real life to use the broad edge for shading.

Currently when I set brush scatter to Pen Tilt, the effect works in reverse: the stroke is scattered when the pen is upright, and gets thinner/sharper when the pen is tilted. This is exactly the opposite of what I want.

This is BY FAR my most wanted feature and the reason that I will never be able to use Photoshop over Clip Studio Paint, despite Photoshop being far more powerful in many ways. Please consider adding a way to reverse the effect.
