Good question, I would like to know that as well! At least they must have been planned for it, because you can't only select them from the main screen, there is even a way to load them directly via the main icon/command line (I don't know how exactly though anymore). Of course it doesn't work, only the option is implemented.
And I know they also aren't included on the CD32 cd's (which is the best Amiga-version, provided when you use the patch to use it on a "normal" AGA-machine).
