More than one sprite sheet in a screen?

Hi,

If I want to add a sprite sheet to a screen, I create a CCSpriteBatchNode with a texture atlas, and then I create CCSprites from it and add them to the SpriteBatch.

That’s easy. But what if I want to add more than one texture to the sprite batch? should I create more spritebatchnodes or there is some way to add more textures to just one sprite batch?

Thanks
