More than 1 Title Set on 1 DVD

[91638]

I want to put more than one Title Set on one DVD. Each Title Set consists of

a) Main Menu
b) Movie
c) Chapter selection

Is it possible to put some Title Sets on one DVD without reauthoring, this means to import the complete Title Set with a, b and c and to put a Main Menu in front of these Title Sets with the opportunity to select one and jump to the main menu of the selected Title Set?

Thanks for every hint.

You need a Title Menu in VMG Domain with buttons to select intended Root Menus and a Root Menu for each VTS with buttons a) b) and c).
