Schedule alarm via wm_schedule function

It would be nice to have a function which would allow to schedule an alarm which would wake up the watch. Possible usage is to create a countdown timer or an alarm clock directly in the watch face. The alarm function would wake up the watch and run a function (e.g. vibrate). Example of the implementation:

vm_schedule { action="alarm", delay="3600", run_function=myfunc }

That would set an alarm which would wake the watch in 1 hour time and run function "myfunc". The watch can be woken up by setting an Android alarm as described here:
