(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.

Nevermind, I just made a script to write the above script for me. It works by detecting all scenes in the project and then writing a C# editor script with the correct functions.
