Anisotropic shading for short hair od dogs


I am relatively new to the Unreal engine and currently working on a dog with very short fur. I was wondering whether there was a way to cool control the direction the specular highlight within Unreal, to shape the highlights at all?
A few 3D packages allow you to export flow maps for anisotropy. Any tips how to achieve this effect would be greatly appreaciated. I have attached an image of what i am trying to achieve.
