Apple Logic Pro /LogicExpress Discussion

I got Tiger tonight and installed and started using it.  One of, 
actually only the reason I moved to Tiger is I want to use Automator 
to save time of executing repetitive task working with Logic.  

The action I want to program is change time length of the multiple 
sound files and save them to specified folder.  I just started 
learning Automator, but if I am right, that action cannot be 
programmed.  

Is it right?  Cannot Automator program such action?
