Sorry not interested. The feature you requested is not of general use because it is typically just done once and there is already a way to do that via the TOC editor.

Building a TOC is typically done once at the end, so automating it is not useful. If you must have something that can be done in an automation list, create your own plugin that does what you want. Stripping a 3 level TOC down to a 2 level or single level TOC is quite easy to do in python, so a plugin would be relatively straight forward.
