In the gitlab wiki's can you add an auto-indexer?

So in gitlab you can use [[_TOC_]] to display a table of contents for the current page - which works on headings.
But I want to have a hierarchy in my wiki like:

<home-url>/Project1
<home-url>/Project1/Tools
<home-url>/Project1/Debugging
<home-url>/Project1/Debugging/GDB
<home-url>/Project1/Debugging/MSVS

Such that in the Project1 page I get an index (links) to each section similar to the table of contents layyout - e.g.:

 - Tools
 - Debugging
    - GDB
    - MSVS

I can do this manually, but that’s a pain to maintain. Is there some automatic tool to do this for me like TOC?
