Lock image to location on magic sheet

Constantly building new sets for Film/TV. While making magic sheets I add set maps jpg images as a "background" most of the time but sometimes I have to add a set and in doing so add image. It would be very helpful to make an additional image lock to location so it does not move when in editing mode. 

Let me know if this is possible  thanks.  Also rotation of background would also be helpful.
