Another request :) - This time for location of PNGs

When using PNG as "overlay images" it would be nice to be enable to have them on top, as you see on this picture then PNGs are always on the bottom but would be nice to have them on top. It's possible today but it's horrible because then you have to create always new images with a lot og emty spcace and with dynamic menus you know that's a waste of time.
Thanks to you all.
