Is it possible to do either of the following things:
- Add a background image to a heading style
- Add a rounded rectangle shape in the heading style where the text is in
Note that this has to be a heading style, so every time this specific style is used, the same background image has to be displayed (or the background has to be solid with rounded corners).
I've looked everywhere and it seems you can do this in the header of your document but not in headings/chapter titles.
