Is it possible to load an image as a layer on top of another image? I know that C1 is a raw processor and this kind of question is in the regime of Photoshop. However, image blending has become more and more frequent (HDR, focus stacking, compositing, etc). Having this simple ability in C1 seems like a logical extension of the 'heal and repair layer' ability. Instead of just referring the source and target from the same image, one might be able to load two images in the viewer and use them for the source and target regions.
