FBX with textures import

This is really getting to my head. When I import an fbx inside of Unity, Unity simply does not assign any texture to them unless the textures are in the Assets folder. But as soon as I move them to a textures folder inside of Assets folder, Unity simply doesn't apply them automatically. This will make it difficult to manage all the textures in a full game, I need to have them in several folders assigned to different kind of objects!

In the Bootcamp demo Unity comes with the textures are in their own folders and subfolders.

Why can't I accomplish this.

I guess in bootcamp demo they were assigned manually from that folder. You can always write some kind of asset postprocessor to accomplish what you want.
