Create a Display Object from 2 or more images?

I am creating my own engine that works with Tiled. It is already running faster than anything out there.

The feature in the topic would be extremely useful for me, and could help improve performance a lot. Especially in scenarios where an image simply repeats itself over and over. A good example is a floor/platform that is generated from the same repeating blocks/tiles. Another scenario is backgrounds that are made out of many objects/tiles. 

It would be a lot more efficient if I could create one display object from many images(either identical or different ones) instead of creating many display objects.

Is there any way of doing this?

Insert them into a group then use the group to control the object

I am already doing that. This helps controlling them, but the app still renders them as individuals and that  takes _ way  _more cpu than needed

You’ll have to wait for graphics 2.0
