Instant resume

Hi.
So I want to implement instant resume for the whole channel. I mean I want to save the last opened screen and then, for example, when I press the "home" button and  then return to my channel it will not start from MainScene, but from that last opened screen.

Is there something similar to what I want to do so I can use it like an example? Or maybe does someone have any advice where I should start and what I have to do first?
