Importing M4B M4V into iTunes

I just tried to create a rule to directly import a bunch of lectures from The Great Courses into my iTunes with Hazel. The rule criteria included partial file name and extension matching, with the work to "import to iTunes (library)" but nothing happened.
Of course, when I changed to "move the file to folder `Automatically Import to iTunes`" the end result was as desired. I'm just wondering if there was some way to get these files imported directly, rather than the folder option.
