limit number of savings with multi-frames on a page

To simplify more again SScan, it'd be fine to avoid to do several savings for each frame defined in a same page (or to have to numerise twice or more the same page, or to have to use frame-tool with Gimp). I suggest : to enable several frames on a numerised page or to create a function "duplicate this page" wich create the same page where you apply the frame on a another part. A the end : one simple saving with the automatic managment of names.
