Show file location folder in iTunes columns?

I understand why ITunes does not have this option, as most regular I tune users have all their music in ITunes folder.

But for someone that has lots of music files stored in different folders in different external drives, this option will be great. Due to my music data size, and how I like to manage them, I keep my music in three separate external drives and access them all through I tunes.

As of now, you have to get info to each song to know where it is.

Thanks
