Importing models with multiple textures...

I finally figured out how to add textures to assets in Unity. But I have a big problem. I have one model (asset) that has multiple textures. Like there is one texture for the head, another for the arm, another for the legs, and so on. Is there anyway to get around just having one texture? Because if I add just one, one part will be textured and the other will be all white. Or is there a way to apply multiple textures? Thanks for the help! -Rov
