Customize UL list in editor

How to add styles to editor to generate custom UL list? I know it is possible with this:

but I want to generate UL list with specific structure. Like this:

<ul class="icons">
   <li>
      <i class="right"></i>
      List item 1
   </li>
   <li>
      <i class="right"></i>
      List item 2
   </li>
</ul>

So I add two lines of text to the editor, then click on specific style and it will generate this HTML code.

Thanks a lot for help.
