How to Always Run Loading Scene when I hit the Play button

Is there a way to get Unity to run my loading scene when I hit run, as opposed to the scene that I am currently editing?

My home scene won't run unless the loading scene has been run first. So every time I run I have to open the loading scene. Then when I am finished I have to load the scene I am working on again. It's a lot of navigation.

 

Code (CSharp):

1.     [MenuItem ("Edit/Play from Prelaunch Scene %l")]
2.     public static void PlayFromPrelaunchScene () {
3.         if (EditorApplication.isPlaying == true) {
4.             EditorApplication.isPlaying = false;
5.             return;
6.         }
7.  
8.         EditorSceneManager.SaveCurrentModifiedScenesIfUserWantsTo ();
9.         EditorSceneManager.OpenScene ("Assets/YourStartLevel.unity");
10.         EditorApplication.isPlaying = true;
11.     }

Put this in a script. Then you can assign a shortcut in the unity shortcuts menu ( search for prelaunch ).

 

Thanks for the script! It's not quite what I am looking for as I am hoping to get back to what I was editing before launching.

To edit a dialog I actually have to drag the prefab into a scene and navigate to what I want to edit. I am trying to not have to repeat that process every time I run. It wastes a ton of time.
