Is there a way of updating a template in different styles

[tazattitude]

I have 4.0.1 and was just wondering if there is a default way or a mod that you can make changes throughout all the styles without editing one by one.

For example...
I have 7 styles I want to add a mod to.
I now have to go through all the postbit_legacy templates and look for
<dl class="userstats">

and place below it...
{vb:raw post.crowns}{vb:raw post.champtext}<br />

What I would like to do it look for
<dl class="userstats">
and replace it with
<dl class="userstats">
{vb:raw post.crowns}{vb:raw post.champtext}<br />

Thanks in advance
