In Windows 7, if you right click on an MP4 file, you are able to edit values such as the Star Rating, Parental Rating, etc, etc.
These values are saved in the MP4 file, and are readable by both the OS and WMP when the file is added to it.
Is there ANY way to add such tags using MP3Tag? I haven't noticed a way, but I ask anyways, as I notice that the tags seem to be supported for wmv files as noted here:

But they're not writable into MP4s even though Windows/WMP supports them?
