Advanced Link Options

Hi all.

I need some help to my new clickbank project!

How can I set a advanced link options to my site?

I have 3 different layout people can promote!
site.com/a.html
site.com/b.html
site.com/c.html

How can I set it up, where people can choose the layout they want to promote and still use the same clickbank id?

Here do you see a site there can do what I mean http://www.digitalsatellite.tv/affiliates.php

Any help here?
