Painter 2020 - Express Paint question

I saw a Skip Allen tutorial about Express Paint with Painter 2017.  He showed that using a flow map with the gradient tool using Heavy Dabs changed the appearance of the dabs, and they were effected by the flow map.  I've tried various versions of this in 2020, but can't seem to get any change in the behavior of the Heavy Dabs (or any other Express Paint type).  Does this still work?  Skip's tutorial:  https://www.youtube.com/watch?v=4AiJRNQCmc0

Thanks!
