'Selective editing' for image-to-image and other functions.

I feel this tool is incredibly useful for image generation. The ability to draw over an image, and the parts that were drawn over are subject to image generation, while the image outside of it is taken to account, but not changed. Not sure how feasible it is with Civitai, but I’ve been able to do it with Simple Diffusion, so having it on the site would be both neat and useful.
