Feature: the option "Link level to style" in Outline Numbering
The Open XML (DOCX) feature "Link level to style" is not supported by Open Document Format.
You find this option with this way:
Home Tab |Parapraph | Multilvel list | define new Multilevel list | press more| Link level to style
Open Office only supports to link paragraph styles to the levels of the build-in list of headings used by the ToC. For no other outlined list the levels can be linked to paragraph styles.
