How can I extend the parameters to add also direction of the rotation ?

Code (csharp):

1.  
2. private void RotateDegrees(Vector3 degrees,
3.         params Animator[] anims)
4.     {
5.         Quaternion quaternion = Quaternion.Euler(degrees);
6.         foreach (var anim in anims)
7.         {
8.             anim.transform.rotation = Quaternion.Slerp(anim.transform.rotation, quaternion, rotationSpeed * Time.deltaTime);
9.         }
10.     }
11.  

For example using this method:

Code (csharp):

1.  
2. RotateDegrees(new Vector3(0, 0, 0), animators[0], animators[1]);
3.  

But if I want to make that animators[0] will start rotating from right to left and animators[1] from left to right ?
And do it in one line like I'm doing now but with a simple way to decide to what side it will rotate each object.
