Restarting a tween with different start position

[Ketchup_Master]

I have 4 reusable tweens that should move the target relative to its current position.

Each of them is basically the same as this example one, but for each cardinal direction:

goLeft = this.tweens.add({
  targets: gamePieceSprite,
  x: {value: '-=64'},
  duration: 1000,
  paused: true
});

Since I want to be able to use these tweens multiple times, I use the restart() method, which I want to play the tween from the sprite's current position, but even when I change the position of the sprite, when I call the function to restart the tween it plays from the coordinates at which it first played and not where the targeted sprite currently is.

var pathCounter = 0;

testPathText.on('pointerdown', function(){
  if (pathCounter % 2 == 0)
  {
    gamePieceSprite.setX(startTile.x);
    gamePieceSprite.setY(startTile.y);
  }
  else
  {
    if (levelStartRotation[level] == '1')
    {
      goLeft.restart();
    }
    else if (levelStartRotation[level] == '2')
    {
      goUp.restart();
    }
    else if (levelStartRotation[level] == '3')
    {
      goDown.restart();
    }
    else if (levelStartRotation[level] == '4')
    {
      goRight.restart();
    }
  }
  pathCounter++;
});

Is there any way for me to update the start point of the tween so that restarting it doesn't just start from where it started before?
