Jerry Bishop as the announcer of Judge Judy

Hi,

According to IMDb's style guide, announcers of non-fiction shows should be listed under "additional credits" rather than as actor credits.  Accordingly, I added Bishop and the other two announcers to their appropriate sections under the additional credits.  However, Jerry Bishop has acting credits for thousands of Judge Judy episodes, variously as "announcer", "self - announcer", and "voice".  Is there any way to mass delete his acting credits now that I've appropriately listed him as the announcer?  As far as I can tell, all of his credits for Judge Judy as an actor and in self should now be removed and replaced with the credits I've added for him in "additional credits".  Thanks.
