[TYPO3-RTE] bulletlist with span

[Sebastian Fuchs]

Hello RTE-list,

is it possibly to automatically insert span tags into the rte produced 
lists?
Right now i am getting:

<ul>
<li>item1</li>
<li>item2</li>
</ul>

to style these lists with css it would be nice to have:

<ul>
<li><span>item1</span></li>
<li><span>item2</span></li>
</ul>

is there some page_ts config to archive this? or any other way to get 
this output?

any hints?
thanks a lot,
sebastian

ps:
i am working with TYPO3 v4.1.2 and the shipped standart rte.
