Styling tabs in bullet lists

I use a lot of bulleted lists and the default style creates too large a gap between bullet and text. I have formatted my bulleted list with smaller tabs and then saved it as a style. However, when applying the style to other bullet points, nothing changes and quite often when I return to the orginal bullet the tabs have reverted to how they were before I styled them. I have include both paragraph and character in the stles to save.

  1. Can bullet list tabs be changed using styles?
  2. Is there a better way to create different tabs for bullet lists?

Many thanks!
