Moving avatars lips with sound

We did purchase the Complete Characters package, but still i'm not sure :
how can i add a mouth_open morph ( for example, for the speak function ) to the characters that come from
the package? is there any way for me to import the max file that comes with the package, and import only the face into 3DMeNow and back, to create a new morph?
Or do i need to create the morph immediately in the 3DMax? or can i not add head morphs at all to the characters, and my only option is to create my own heads
and with the help of the 3DMeNow, and then add them to the characters?

thanks,
dan
