PDFCreatorGUI: send eMail without "Save as" dialogue

Hi there, I'm aware that with option "AutoSave" this is possible.
But what I like to have is:

1. I print from a Windows7 app over PDFCreator as my printer
2. PDFCreator GUI shows up and I just press the eMail button
   and NO "SAVE AS" dialogue appears but instead the eMail client starts directly.
   It creates a new eMail with my attached pdf-file !

Would you mind telling me if this is possible by changing setup/config (registry) that
No NO "SAVE AS" dialogue appears  ?

Thanks in advance for help/informations
