Setting Board Orientation Axis Angle (e.g. for racing quads with tilted rotors)

Hi there,
I am yet not really sure whether this is possible and how.
According by this article one can define the board orientation in 45° steps: http://ardupilot.org/copter/docs/common-mounting-the-flight-controller.html
However, I want to define an e.g. 7° offset along the pitch axis.
Is this possible so far?

Best, Daniel

Looks impossible, I wrote commit :smiley:
