Copy placed graphics from one object to others

I often have to place graphics onto a stack of identical objects. For example I have 24 boxes of identical product on a shelf. I currently have to place a graphic for the front face, the right face, the top face and the left face on all 24 boxes. It takes ages. If I choose, instead, to export UVs for each box and use that method to apply the graphics, every single UV is different, even though the CAD for the boxes is identical. I know I could just duplicate the first box to 24 different positions but that has it's own difficulties in terms of accurate positioning.

If we could have a way to copy and paste the graphics from one object to another it would be very helpful. Also if it could be possible to make UV's consistent, that would be great too.
