Filter images with Comfy workflow

It would be very handy, if we could search for/filter images generated with ComfyUI and containing a full Comfy workflow instead of the usual A1111 genration data. At some point, some images were displaying a Workflow copy button but it seems none of the images I currently look at are doing so. Since I assume you didn't remove the feature, I guess less people are uploading ComfyUI generated images, hence the huge amount of time taken to find them. Adding that filter would be a huge time saver.
