Is it possible to only show one specific article in Ajax Scroller

I'd like to limit the amount of space article content takes on a page by using Ajax Scroller.  But I don't see a way to include ONLY show specific articles.  I have many pages, so creating a new Category for each article is not practical. 

Hi,

You can't select specific articles but you can show all articles that belong to specific category and then limit number of shown articles.
