Is it possible for the user to add "CUSTOM" conversions to the program?
Not currently...
Our current approach, unfortunately, makes this a difficult thing to add - but it is something that we have spent some time looking at for the Professional version.
So maybe - once we come up with a way to make the underlying structures handle it and come up with a good User Interface to this feature...
