Can you cut out a portion of an .wav audio track from your project timeline?

 I'd like cut a portion of this .wav audio clip; I've already modified some of the visemes in other places so I don't want to delete the entire thing, edit it in Audition and re-import it. I'd like use the razor tool (or something comparable) and cut it while still in Character Animator.

Does anyone know how to do do this? Thanks and Happy New Year!
