How To Go To Previous Scenes ?

In Buildbox2, I can go to next scene using Next checkpoint Option. But am unable to crack how to set the functionality for (Previous Scene) Button. Is it possible to go to previous scenes using a button ?.

PS: I know how to implement this using multiple worlds. I want to implement this in single world.

 

store previous scene name as settings data and use this line

Code:

  this.scene().addLevel(String(Settings.level));

this code will set this "Settings.level" as the current scene

 

Thank you for reply. But here i am talking about Buildbox2. Not buildbox3.
