More GPS Information with Nmea filter

in GPS Features
Hi
is it possible to add some custom information in the GPS Information windows ?. For instance, the accuracy "EPH" ( by the way , you mean HPE or Horizontal Position Error?) is not sufficient in my case.
I would like to show for instance, the deviation of Lat, Lon & Alt Error that we can catch from the $GPGST ( or $GNGST for GNSS) NMEA sentence.
Regards
