How to change scene without the previous scene being reset when you return?

Hello.

I have several scenes and I want to switch between them to keep the data for when I go back to the previous scenes.

Example: scene1 (menu) ---> scene2(not reset) ---> scene1(menu) ---> scene3(not reset) ---> scene1(menu) ---> scene2 (not reset)

I want the scenes where I entered are still active and not reset.

Thank you.

I am sorry for my bad english.
