Here you can create a List Style. The List Styles are organized in the Styles window.
When a List Style is created, a name is assigned to the style. The list style can be applied to paragraphs or assigned to a paragraph style in the Apply List Style section of the Outline & List tab.
Ordered lists and unordered lists created in the Bullets and Numbering dialog or with the Toggle Ordered List and Toggle Unordered List icons of the Formatting bar use direct formatting. They are not list styles.
