You can put a DrawingCanvas object in that position and paste all objects onto it. To scale down the image, you need to move it to a sprite:
DrawingCanvas paste everything..
Wait 0
DrawingCanvas save image
Wait for the previous action to complete
Sprite load image from URL: DrawingCanvas.SavedImageURL
If you want this image to be accessible on another layout, you will need to set Sprite object as global. Or save image in one layout and load it into sprite in another, but I'm not sure it will work.
