I often think that it would be great to make VA work with hand-typed script, although the drive is to make everything work through a user interface (kind of clunky if you're a programmer, but not everybody's a programmer (yet)). It would require quite an effort to interpret script into VA's vast set of actions and the values for those actions, so, something like that gets pushed off. What folks have been doing for years, however, is just exporting their profiles, modifying the xml and then re-importing.
