List of Transforms editable from Inspector

I'm working on Unity 5, and I need to create a list of transforms in order to modify them in the inspector (position and rotation) to emulate a different camera. This emulation is for a demo, like a camera moving on its own during the demo.

I currently have a list of transforms, but I don't know how to make them modifiable in the inspector and change their position at runtime?

Edit: 18/11/15

Here is the solution that if find with a help of a friend of mine more aware of what really does unity, hope it will help you and thanks again for all your reply it helped me a lot :D :

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class MoveCamera : MonoBehaviourSingleton<MoveCamera>
{
    public List<Transform> cameraPositions = new List<Transform>();

    private Transform m_Target;
    private float m_Speed;
    private bool m_Translate;
    private bool m_Rotate;

    public void SwitchToNext(int index, float speed)
    {
        m_Target = cameraPositions[index];
        m_Translate = true;
        m_Rotate = true;
    }

    public void Update()
    {
        if (m_Target != null && (m_Translate || m_Rotate))
        {
            float ratio = Time.deltaTime * m_Speed;
            transform.position = Vector3.Lerp(transform.position, m_Target.position, ratio);
            transform.rotation = Quaternion.Slerp(transform.rotation, m_Target.rotation, ratio);

            if (Vector3.Distance(transform.position, m_Target.position) < 0.001f)
            {
                transform.position = m_Target.position;
                m_Translate = false;
            }
            if (Quaternion.Angle(transform.rotation, m_Target.rotation) < 0.001f)
            {
                transform.rotation = m_Target.rotation;
                m_Rotate = false;
            }
        }
    }
}

I would suggest just a simple public list in your MoveCamera script and then dragging the targets into that list. Doing it this way you have full control over the order of the objects and thus you can do animated transitions from camera position n to n + 1.

public List<Transform> cameraPositions = new List<Transform> ();

Maybe a simple sequence does not fit your requirements and you need a more sophisticated way to decide which position is allowed to switch to which other position. In this case I'd suggest a helper script e.g. CameraTransition.cs. Here you can place your check logic and definition parameters.

Attach this to every allowed target position object and replace the list in MoveCamera by List<CameraTransition>.

Ok lets see if this helps you.(i will write my code assuming you want this) You have x gameObjects in your scene.

You will need a GameObject List. Lets say you get them by doing 

public List<GameObject> myObjectList = new List<GameObject>();
public List<Transform> myTransformList =  new List<Transform>();
myObjectList = GameObject.FindGameObjectsWithTag("YourCustomTagHere");

foreach(Gameobject g in myObjectList)
{
 myTransformList.Add(g.transform);
}

I dont know if this code works, i cant test it right now, but i think the logic is there. Go ahead and try a few things, give some feedback whether you made it or not.
