Is it possible to hatch a closed mesh in cross section drawing - similar to hatching a component?

Running ORD 2021 R1.

I have created a closed mesh for select fill and referenced it into my cross section container file. I am trying to see if it would be possible to hatch the area inside the closed mesh in the drawing model, similarly to how components are hatched in this video: https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/52655/video-hatching-components-in-cross-section. I tested this on a simple component, and it worked. I then tried applying an element template with hatch properties to the closed mesh, but no hatch appeared in my cross section.

Does anyone know of a way to accomplish this hatching? I think my other option is to pattern by points in each and every one of my hundreds of cross-section drawing models...

Thank you,

Andrew
