change sprite about andengineexamples HOT 3 OPEN

I would also like to see this sort of feature implemented.  I am trying to make 
a touch-based grid style game and I want to be able to update each grid tile 
when it is touched.  
It would be much simpler to just do this with a switch of the texture instead 
of trying to stuff some code in that removes the current sprite and then sets a 
new sprite in its place with the updated texture.

Even I am facing the same problem as i have to implement a slot machine with 
3X5 matrix so for that i have to highlight few textures to show the winning 
elements which can be done replacing current bitmap with highlighted one.

Other then that can i get the current visible items of the long sprite

Thanks

Please implement this feature in GLES 2. Add a function to Sprite like 
sprite.changeTexture()
