2D Camera Smooth Follow with Dynamic Offset

I want the camera to follow a target (Player) but with an dynamic offset depending on the direction the Player is moving (or axis input), so the player can see ahead of itself.

I am using Scott Kovacs's fantastic script which worked easily:

 var dampTime : float = 0.3; //offset from the viewport center to fix damping
 private var velocity = Vector3.zero;
 var target : Transform;
  
 function Update() {
     if(target) {
         var point : Vector3 = camera.WorldToViewportPoint(target.position);
         var delta : Vector3 = target.position - camera.ViewportToWorldPoint(Vector3(0.5, 0.5, point.z));
         var destination : Vector3 = transform.position + delta;
  
        // Set this to the Y position you want the camera locked to
         destination.y = 0; 
  
         transform.position = Vector3.SmoothDamp(transform.position, destination, velocity, dampTime);
     }
 }

I have my head roughly around the idea, I will need a variable that is taken from the input.axis and applied as part of the transform.position = Vector3.SmoothDamp(transform.position, destination, velocity, dampTime).

I would like a vertical offset and horizontal offset that work at the same time if the player is moving diagonally.

Any tips would be very much welcome!
