If you want to apply these changes to other lists in your presentation, you can create a list style or update the list style you’re already using. Only formatting changes made in the Bullets & Lists section are included in the list style.
You can create a list style for any kind of hierarchical list, from a simple one that includes just two levels of hierarchy, to a complex one that uses many styles of numbers and letters to define multiple levels.
After you format a level of hierarchy, you update (redefine) the list style to incorporate that level. For example, if your list has five levels of hierarchy, you need to update your starting style five times to fully define the style. The process results in a single style that automatically formats a list with the same number of levels you defined. You can then use that style for other lists in your presentation.
