Video slate

Hi, after reading other threads I appreciate that there is no function for me to directly select a slate image for my videos,, and in most instances this is not an issue as the provided one has been perfect. However my latest upload has given me a slate featuring another actor. I would like to request that this slate be replaced with the profile image that comes in at 04:32 on the video. My page is: Peter Vollebregt - IMDb and the video in question is the 6:18 min video Demo Reel: SHOWREEL | IMDb
