Seed of image variant

I generated 4 images (faster) one of them was really great. I though, “that’s it, just, I should have specified the shirt color” But I can’t get the seed of this specific image generation which is really weird. If I want to tweak the result, I need to regenerate 4 variants again and again, which is a waste of AI resource. When providing image information, the seed of the image would be better than the seed of first one + variant count.
