If you are referring to the multiple step variations often posted for American Smooth then no, there are no international variations posted on this site. There are just American variations. You can view all syllabus steps however with the membership which is pretty cool.
If you are looking for Standard variations you can go here: http://www.youtube.com/watch?v=77eAg7dILtI
The following is a waltz video done by Mirko and Alessia. They have a great syllabus variation for waltz here. You can search for all other variations for standard on youtube.
If you are looking for latin, I recommend Slavik and Karina's video series with Corky Ballas.
Here's a video of one of their cha cha variations: http://www.youtube.com/watch?v=4RgMngpCWwc (This is not from the series but if you search around you can find their variations)
Hope this is at least helpful in you continuing your search for what you are looking for.
