I (think I) understand exactly what you're talking about, as I have wished for such a feature as well. However I'd like to modify this request into one for two buttons. One that would act just as it is now, for when I'm making only one change and don't want/need to back-track down the menu path, and the other that would take me to previous pages in this menu branch.
Of course, as others have said, these are minor items, and would gladly forgo the added features to avoid an overly complex program inviting multiple bugs.
