where is "set tags from filename" feature?

hi all,
as far as I can remember in a former release of exaile there was an option (in the song's properties window) named "tags from filename" or something like that, which was creating tags from the filename of a song, based on some special patterns (e.g tracknumber - tracktitle.ext). Maybe I am not explaining this usage right but I surely was exited with having the opportunity to create the tags for song files with the "right" filenames...
Is there another way to do such a thing now? (using 0.3.2.0 on maverick)
Or is this option coming back?

thank you
