Read multi-page attachments
 

In an outline, I'm attaching some .pdf documents as items. When I click on the disclosure triangle of the parent item to the .pdf, the first page of the .pdf appears. But if I want to read more than just the first page of the .pdf, it appears I have to click on the arrow to the right of the .pdf's title to actually open the document in Preview.

Is there no way to see all the pages of the attached .pdf in OO?
