Weight loss goal widget: ranges (Read 30 times)

The weightloss goal widget is simple and rather nice.  However, is it possible zoom in?  The current scale reads from 148 to 200lbs . . . and that's just for the "green" zone (the 110lbs to 240lbs full range is just scary).  Since my focus is on 167lbs right now, I wouldn't mind if the scale only showed 155 - 185, with 162-173 being "green".
