Created attachment 167003 [details]
Example file from Word with custom TOC.

Attached Word-made document contains a default “Manual TOC”.
When opened in Writer this is not imported as a TOC field.
It also seems like Writer does not have a similar “TOC fillable independently from the documents contents” feature, so maybe first one would needed to be invented.

Steps to reproduce:
    1. Open attached file

Actual results:
There is no TOC, as visible in the Navigator.

Expected results:
Some sort of generic TOC field, retaining the formatting seen in original document.
