Adafruit motorshield V2 servo outputs

Hi

I have a adafruit motorshield with my arduino uno running 4 rumble motors connected to the DC motor outputs.

The shield also have 2 servo outputs that I would like to use, but I cant figure out how to use them? 

All other pwm outputs mentioned in the docomentation are based on the output pins of the arduino board directly.

Im I missing something here? I pretty sure I have read everywhere to fins this out. Is it not possible to use the motorshield servo outputs at all?

Thanks!
