(Please bear with me; I was looking around but due to complexity and probably lack of a simple way to describe the problem I did not find an answer anywhere.)
It is possible to create paragraph templates (but I suspect this is the same for any other hierarchical template) that derive parts (or all) of their settings from their parent template. I chose to create a template “Heading” and assigned it a specific font and derived a “Heading 1” form that parent, using it to create “Heading 2” and more further down the tree. I never changed the font in any of the children. This is working as intended.
If some dummy is setting any unspecified parameter in one of the derived children (e. g. setting the font name) it seems to be impossible to reset this parameter to “unspecified, take it from your parent” again (either due to me being too dense to find out from the menus and the available help or the function really missing from the UI). The only workaround I have found is recreating this template and replacing the modified template with the new one or using Word or Textmaker to edit the file (having the usual side effects). Neither seem to be a good solution.
Is there any other way to reset parts of a template to the “unspecified” state?
