Show menu headers in HTML Sitemap?

Hi!

I was wondering if it's possible to add text menu headings to the HTML sitemap? They're not links, but they help organize the links into a human-readable format, which is important for HTML sitemaps.

For example, I have the following menu, where "Learn" is a menu heading:


And this is how it shows up in the site map:


Obviously, these pages aren't sub-pages of the "Kids Area", but because they are level 2 under a menu heading, it appears as though they are under the kids area. It's confusing and misleading.

How can I fix this?

Thank you!
