Reply to Adding BPM on Traktor Pro 2 Software

When I load up a track for the first time, Traktor auto-writes a tag on the song that does not include BPM. How do I manually attach the BPM to songs on Traktor using my Mac? I try and right click and all I get is [Import to Collection/Show in collection] ? I need to know the BPM of my tracks without having to load them to see.

Thanks in advance guys... and gals.
