Headings with Simple Link Directory

Hi,

I am using your plugin together with plugin https://www.ads-software.com/plugins/simple-link-directory/

Unfortunately, I can’t find a way to NOT display the List Title in the TOC, or anything other than a h2 heading.
This causes issues as it sometimes doesn’t make sense in the hierarchy to have the List as h2.

Any idea how to modify this?
Thanks
Robin
