There are three easy ways to define bullet lists with LibreOffice:
- Start a paragraph by typing "* " (with the correct option active)
- Use Shift-F12
- Use the button in the format toolbar
And I currently think they are equivalent. I can define list styling for paragraphs having a list style attached, or for list started by applying a list style of a given paragraph (either from the corresponding button in the format(style) toolbar or from the style side panel) but I’ve not found how to change the default styling used with that easy way. I can change the style for an existing list, but any new list get the default style.
I’ve even tried, unsuccessfully, to use conditional paragraph style, and it didn’t work. (But conditional paragraph style seems buggy; I got lot of glitches when playing with them, and their usability found a all time low when I found out that I couldn’t save them, see https://bugs.documentfoundation.org/show_bug.cgi?id=137166)
