rating system or image shelf

while using Firefly, I find my self wanting to mark or save some aspects of the image for later review. It would be great ive queries were saved or tied to the image before submitting to the galley. on a similar thought. if you could save a selection of a image to allow that part to be used in the next step (prompt or style change. IE: creating a robot in first wave - selecting the feet and head to be used but re generateing the rest of the image.
