Is it possible to move the origin of each image in the editor, the green and red arrows, that the image will rotate around in the editor. I know I could modify the art not to have loads of white space and get the actual image center, but thats a lot of messing about. Would be much simpler if I could just drag the arrows onto where I want to be able to rotate the image in spine.

Just for setting up purposes, often when I drag an image in, the arrows are way off the image and it makes rotating the image a bit more tricky to get just right.
