Metadata101 - Replace All Episode Thumbnails

Is there a way to replace the All episode thumbnails with just one image? I was just looking at metadata101 and I don’t see a way to replace them. It would be convenient to be able to replace all episode images with an image of choice to avoid spoilers on reality competitions like Survivor, Big Brother, and The Amazing Race.

The hide spoilers option in Infuse hides all images and descriptions for all shows which is not what I was after. Just one image to replace all the episode images for the entire show.

Something like
Episode poster

Have you tried the Hide Spoilers option?

I’m trying to get rid of only the spoiler images without actually bluring them.
