Wrap additionial registration fields into div

Hello,
In s2member I can add new registration fields. PRetty cool thing, now I can know everything about my customers ]:>
I would like to put the whole registration form on my frontend and style it a little.

Nice thing is, when I add a divider (start new section) it’s wrapped in a div. But only the section title. The

s where forms are located, are not in that div.
Nicer thing would be, if the divider and the whole section of

s would be in that div, so I can position and style it in any way I’d like to.

Can someone point me to the file or method how I can do that? It’s only matter of placing somewhere else, I hope :)

Thanks from advance!
