Close margin shortcode spacing

[ekellagher]

I would like the close margin spacing between a Heading and a Text style to look like the default like break spacing.
In the following screenshot the first course title "Jewish History" is an H2 and the course number is the Lead Style with the close margin shortcode between the two

The next course title " Holocaust ..." and the course number are both the Lead Style with
spacing but this is not accessible since we need a heading formatting for the course titles on the page.

Is there a way to use the close margin shortcode to create the look of a soft return while using the heading formatting for accessibility?
