Hey Beau,
If I understand correctly, you want to control the direction of your image per face, right? That way the bricks look like they are laid in real life, or at least generally like that. If I was a betting man (and I am) I would say that is not currently possible. Since these values are applied to the body, they will remain consistent. That being said, you can easily right click on the material that you just created and choose to duplicate it. If you go back in and modify the rotation again so that it is now lined up the way you want, you can then apply the new material to the face of interest and get the look you want. I know it is a few extra clicks, but I'm guessing this is the best/fastest way to go about doing this at the moment. I'll bounce this off of some others to see what they have to say.

Let me know if you have any questions!
James
