Apple Logic Pro /LogicExpress Discussion

Hey, I'm using L8, and am cropping a bunch of audio files that I then  
want to have start at measure 1. Is there a "tie to SPL position"  
command or something that I can't find?  I can use combos of cntl,  
shift, and arrrow keys to get a precise starting point, but a "snap  
to" command would be a LOT easier.

Thanks,

Gregory
