How to control segments with SevSeg library

Question

The SevSeg library by Dean Reading seems to have a keyword to control individual segments on SSD's. I am using four common cathode, single digit displays. Does anyone know how to program individual segments?

#include "SevSeg.h"; 

SevSeg sevseg; 

void setup() {
  // put your setup code here, to run once:

  byte numDigits = 4;
  byte digitPins[] = {2, 3, 4, 5};
  byte segmentPins[] = {6, 7, 8, 9, 10, 11, 12, 13};
  bool resistorsOnSegments = false; // 'false' means resistors are on digit pins
  byte hardwareConfig = COMMON_CATHODE; // See README.md for options
  bool updateWithDelays = false; // Default 'false' is Recommended
  bool leadingZeros = false; // Use 'true' if you'd like to keep the leading zeros
  bool disableDecPoint = false; // Use 'true' if your decimal point doesn't exist or isn't connected. Then, you only need to specify 7 segmentPins[]

  sevseg.begin(hardwareConfig, numDigits, digitPins, segmentPins, 
    resistorsOnSegments,
    updateWithDelays, leadingZeros, disableDecPoint);

}


void loop() {
  // put your main code here, to run repeatedly:

  sevseg.setSegments();
  //sevseg.setNumber(1234,0);
  //sevseg.setChars("");
  //sevseg.blank();
  sevseg.refreshDisplay();

}

You can't with that library. The author has not provided any public methods that will do the job.

There are private methods (segmentOn and segmentOff) that might be usable, but you would have to modify the library to be able to access them.
