BPM Counter in Logic Pro?

Is there an analyzer that will try and determine the BPM's of a raw audio file being played in Logic's sequencer? I guess what I want to do is take some audio files I have and turn them into Apple Loops setting the file's at the appropriate BPM of the audio itself instead of converting it to whatever I chose to. I was hoping I could play it in Logic and have Logic determine what that BPM is and then save the apple loop with that Logic calculated BPM. Anyone know if this is possible?
