Creating a Report and PDFing it with Security

Using VBA in Access 2007 I am writing code that will take various
information from forms and tables to create a letter tha will be sent
to customers. When you have the letter ready it will print a copy of
the letter and save a PDF copy of the to a certain directory. All of
that is working it working correctly. One step I would like to add is
to make the PDF letter Secured. In Access I can do that by going to
the Acrobat > Create PDF menu item after I ahve set the security in
the Acrobat > Preferences > Security Menu.

Is there a way to have the code include the Security setting when I
use the DoCmd.Output command or any other command?
I am have Access 2007 and also have Adobe Acrobat 9 Standard install.

Thanks
