CMS View full article in sub-sections, but not the main page. Is this possible?
 

Imagine my section hiearchy is,

Main Page>Specifications & Brochures> Honda> ATC250R>-Article.

I would like for my full article to display when you click the "ATC250R" section, on my section list widget. Instead of just getting a preview and then having to click read more, to see the full content of the article. But, I don't want the full text of the article to display in the higher level sections, such as the Honda one, the Specifications & Brochures, or the Main page. I want all of those to retain just a simple preview.

Any way to make that happen?
