Can PSU power cycle if Boot OK isn't raised?

I've been working out how to work with the 'AUDIOPHONICS PI Power Management / Power supply for Raspberry Pi' by raising the Boot OK & Shutdown GPIOs, and monitoring the Shutdown GPIO in case the power button is pressed. But one area that I'm having trouble with is that I'm using network boot, and sometimes the Raspberry Pi fails to boot.

What would be great would if the PSU board could power cycle the RPi if the Boot OK GPIO isn't raised within a time limit as a form of boot watchdog.

Is that possible?
