Different crops modes per device/platform (same picture)

Hi, I would like to know if it is possible to set different image crop modes under the same picture but different per device/platform (Desktop/Tablet/Phone)

Example: I have a picture that I set/keep on crop mode: none, both on Desktop and Tablet mode it looks great out of the blue. But without a crop it just looks way to small (zoomed out) on mobile phone. When I go into responsive editing and click on the mobile icon and crop the picture into portrait mode, it looks brilliant on mobile phone aswell! Problem is, it now also forces that crop mode onto Tablet Mode and Desktop mode, making the pictures hugeeees on both platforms. Is there a way to set platform specific image crops and image sizes without one or the other.

Same question for the divider (line) thingy.
