Hi Theresa,
The good news is that you can generate reports for certain packages; it just needs to be done with a customized report template instead of the radio buttons for "Selected Items" or "Current Selection." You've probably noticed that there is no tabbed view for packages, and the project browser only allows you to select one item at a time.
As an example, the Project Specification Word report template starts out with a $repeatPackages keyword below the table of contents. If you've got a particular package you'd like to exclude from that report, add a conditional statement to that line:
$repeatPackages where not Name = 'YourPackageName'
You can find more information about conditional statements in the Custom Reports User Guide, available by clicking Reports / Custom Reports on the ribbon bar, or if you'd like more detailed help, shoot us an email addressed to support@serlio.com.
