ability to choose one primary image and modify

It would be wonderful to have the ability to choose one primary image from a group of four and then have the flexibility to make modifications to that particular image. These modifications could include adjustments to color, focus, blur, changing the person or object, or altering background elements, etc. This process would generate a new set of results and include the original image selected. For instance, in the image provided, the first dog is perfect, but it would be great to change only the color of its fur or the background.
