Side Slope Annotation (Draw Slope Pattern) in Open Roads Designer

Hi everyone,

I'm using Open Roads Designer Connect Edition - 2019 Release 1 - Ver 10.07.00,

and I'm watching video Side Slope Annotation at link: https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/37274/video-side-slope-annotation

But I don't understand how to make Feature Symbologies -> Grading -> TL_End Cond Hinge as picture below:

+ Could you please let me know how to do that?

Thank you so much.
