Tangent normal maps and textures

Hi is it possible to have a tangent normal map and a the texture of an object combined into one draw call

With a single directional light.

Despite what that suggests, you can actually use normal mapping for up to four point lights in that first pass, too, but you have to write your own non-surface shader for it.
