Double Whammy - Whistling and Sibilance

I have a double whammy situation.  One of our narrators has sibilance as well as makes a whistling sound occasionaly.  I have tried a few effects in Audition to remove these sounds but to no avail.  (Captured Noise Print, then Noise Reduction, Sound Remover, De-Esser, etc.).  Of course I could paint the "Esses" and  "Whistles" out - using the Spot Healing Brush Tool, but I have 7 files to edit and these whistles are omni-present.  Pease Help!

I am attaching a sample audio clip where they are very easily visible in the Spectral Freq Display.  I would really apreciate it if someone could please send me step-by-step instructions (or a link to a video) on how to isolate and remove these sharp pitches from an entire file in just a few clicks.

Many thanks!
