Is there any way to show in the inspector a scene with the possible zones to spawn the player?

Question

I'm trying to make an intiutive inspector to select a scene and the possibility of select a "zone" as well to the player spawn position in the scene selected.

Recently I got show Scenes in the unity inspector following this tutorial: https://forum.unity.com/threads/how-to-link-scenes-in-the-inspector.383140/

My class currently:

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

public class ChangeScene : MonoBehaviour
{
    [Scene] [SerializeField] private string nameScene;  


    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Player"))
        {               
            LevelLoader.LoadLevel(nameScene);
        }
    }
}

Now I want that depends on the scene, the "zones" of this appear automatically to select one.

For example, if I select a scene called "World01", appear the zones of this specific Scene like a Enum or another way.

Example Image 01

Example Image 02

Use a customeditor to check every scene and show differents enums... is discarded

Is there any way to get that?

Thanks!
