In Acrobat v8, you could choose to create a PDF Package that allowed you to choose whether to use a default cover sheet or use the first PDF file (in its entirety) as the cover sheet (see http://www.acrobatusers.com/articles/2006/10/pdf_creation_features/index.php and http://www.acrobatusers.com/blogs/tedpadova/2006/10/11/pdf-packages-and-learning-modules/).
In Acrobat v9, it no longer appears to be an option to choose a cover sheet -- the default cover sheet is [i]always[/i] a part of the portfolio. I am happy to say that I have been able to successfully create a Portfolio that emulates a v8 PDF Package in that I can define the first file from the portfolio file list to be initially displayed. To boot in v9, this file remains a part of the portfolio file list, which I think this is an improvement over version 8 which made the first file the actual cover sheet (which was a little odd if you didn't want an actual cover sheet but did want to define an initial document to display; when the audience navigated away from a "document" cover sheet, not all of them realized that the document was not a part of the package's file list).
However, [i]I was wondering if there is a way in Acrobat v9 to omit the default cover sheet (to reduce file size) or select a custom cover sheet in addition to any other files that are desired to be put in the portfolio file list.[/i] I know that there is a customizable "Welcome" page in v9, but that page can only be seen by Reader/Acrobat v9, and the portfolio creator may desire that the initial display always persist across sessions (the Welcome page can be dismissed from being viewed across sessions by selecting "Don't show Welcome Page again").
