WR44 monitor cellular data usage

I would like to know if there is a way to monitor cellular data usage on the WR44. The page Network Status / Interface / Mobile shows a counter for data recieved data sent. These are however not resetable. I would like to monitor data usage so as not overshoot my data package.

management–>network status–>interfaces–>mobile–>advanced–>ppp 1–>{stuff which includes clear total data transferred}
