I have some Javascript files that I use to manage my library in iTunes in Windows. I've successfully edited Track Name, Album Name, and even the Year fields, thanks to knowing which properties to use for the SelectedTracks object, but I can't seem to locate the property for the "Sort As" album field.

I found this link, which has proven to be a big help for the most common fields, but does anyone know where I can find that elusive "Sort As" album field? I've done a lot of searching, and can't seem to locate it. Alternately, is there a way I can return all of the properties for a given object at the single track level? I found getOwnPropertyNames(), but it doesn't appear to work at that level.

Thanks!
