(Editor Scripting) Is it possible to generate MenuItems?

Hello reader!

I've been experimenting with Unity Editor scripting and I was wondering if it is possible to generate MenuItems with code. As in, not having to write:

 [MenuItem("Open Scene/TestScene1")]
      public static void OpenTestScene1()
      {
          OpenScene ("TestScene1", "Levels");
      }

For every single MenuItem I want to create.

I want to be able to automatically generate a Menu Item to open any specific scene in my project, without having to navigate to them or having to add them to the script manually.

I already have this script:

 using UnityEngine;
 using System.Collections;
 using UnityEditor;
 using System.IO;
 
 public class EDEX_SceneMenuItem : Editor 
 {
     [MenuItem("Open Scene/Opening", false, 10)]
     public static void OpenOpening ()
     {
         OpenScene ("OpeningScene", "Menus");
     }
 
     [MenuItem("Open Scene/Credits")]
     public static void OpenCredits ()
     {
         OpenScene ("Credits", "Menus");
     }
 
     [MenuItem("Open Scene/Gallery")]
     public static void OpenGallery ()
     {
         OpenScene ("Gallery", "Menus");
     }
 
     [MenuItem("Open Scene/Menus/Character Select")]
     public static void OpenCharacterSelect ()
     {
         OpenScene ("CharacterSelect", "Menus");
     }
 
     [MenuItem("Open Scene/Menus/Level Select")]
     public static void OpenLevelSelect ()
     {
         OpenScene ("LevelSelect", "Menus");
     }
 
     [MenuItem("Open Scene/Menus/Main Menu")]
     public static void OpenMainMenu ()
     {
         OpenScene ("Menu", "Menus");
     }
 
     [MenuItem("Open Scene/Menus/Custom Game")]
     public static void OpenCustomGame ()
     {
         OpenScene ("CustomGame", "Menus");
     }
 
     [MenuItem("Open Scene/Menus/Options")]
     public static void OpenOptions ()
     {
         OpenScene ("Options", "Menus");
     }
 
     [MenuItem("Open Scene/Menus/Title")]
     public static void OpenTitle ()
     {
         OpenScene ("Title", "Menus");
     }
 
     static void OpenScene (string name, string subfolder)
     {
         if (EditorApplication.SaveCurrentSceneIfUserWantsTo())
         {
             EditorApplication.OpenScene("Assets/Scenes/" + subfolder + "/" + name + ".unity");
         }
     }
 }

Thanks in advance.
