Why do I have to wait for it to recover all faces when I only selected one. Too slow

Please let me refine the subject mask and face selection before tying up my computer performing useless tasks.

After you select the Face or Faces you want refined it only refines those. Click on the Select button next to the Recovering X of Y faces and you can deselect as many as you want.

Yes, I know that thanks. But if the AI detects 65 faces (in a crowd) and I only refine it to recover 2 faces, it still churns away FOREVER as though it is still looking at all 65 (even though it only refines 2 in the updated image).
