Preserve navigation\state of viewControllers

Hi.
How can I preserve the state\navigation of a single section?

I'll try to better explain.
I'm tapping on section one, then I'm push some viewControllers. Then I'm slide the menu and go on the section two. Now if I slide the menu and tap back to section one, the menu returns to the first viewController of the stack. It will be great if I could return to the last viewController pushed before to switch on the section two...

Thanks.
Francesco
