Is there a way to automatically cut out all silent areas in a region

Hi All,

I'm doing a 4 hour narrative, using Logic Express 9.1.8 and I was wondering if there was a way to automatically cut out all silent (or unrecorded) areas in a region... rather than make each cut manually.

I do know there are other recording options like "Punch on the fly", etc. but this is my preferred method of recording.

I've added a screenshot of part of the region below, just to clarify what I'm asking (in case the wording isn't 100% accurate)

Thanks very much! 🙂
