Specify a class or id in UL tag

Hello,

i would to create a specific style for bullets and numbering in fckeditor.
But i don't find anything about this in the manual.

default type (when i click on the bullets button):

<ul>
    <li>abc</li>
    <li>def</li>
    <li>ghi</li>
    <li>jkl</li>
</ul>

but i would to configure fck editor to do like this (when i will click on the bullets button in the toolbar)

<ul class='bullets'>
    <li>abc</li>
    <li>def</li>
    <li>ghi</li>
    <li>jkl</li>
</ul>

is it possible to configure this ?

Thank you in advance for your help .

Yann.
