Can not be done in Powerdirector.
Powerdirector has a very strict menu structure.
You can not change the Main Menu other than the background image.
You can do much in the Scenes/Chapter menu. You can have Chapters or Titles. You can also have Titles with chapters.
You add a Title in the create disk module on the content tab.
