V551: Battery Meter via Number rather than Picture

Hello

At present, my V551 displays a battery meter picture. The
picture has up to six small, vertical, solid tick-marks to
indicate the charge status of the battery. Can I replace
this picture by a number (from 0-6, or as a % 17, 33, 50,
67, 83, 100)? If so, how?

Thanks,
