Question about External Data Provider
 

In the past i have used the external data provider to provide content from a specific forum to other websites via RSS like this: http://www.eclipserecords.com/forum/...ml&forumids=11.

Is it possible to also specify the feeds by thread prefix in some manner as follows: http://www.eclipserecords.com/forum/...1&prefixid=foo

I can't find anytign about it in the documentation but would expect to be able to do this.
Thanks :)
