Hide Post (not just picture) from Gallery

In my models/loras I found an option to hide user-images from the model- gallery. To have this is great, and usually enough, but yesterday an industrious user used the on-site generator to create a few dozen posts, containing a handful of pictures each - mixing in other styles and after the initial post, my Lora has nearly no influence - making this an odd example for my lora's gallery. I remove them by hand, one picture at a time until the post is gone, but it would be easier if a bulk- "remove whole post" -option was available.
