Show "first slide" of next block at end of current block

As current users of PowerPoint in presentation mode, my presenters ALWAYS have a preview of the "next slide". When they are trying to learn Presenter, they commented about not having that full visibility into what is coming.

While showing the collection of slides in a given "set", can that same window ALSO show the first slide of the "next set" in that same window? I suggest it shows a separator bar with the words "next section starting slide" on it then show that next slide just below.

That feature would FULLY REPLICATE the last remaining advantage we see to using PowerPoint. My users don't want to transition until we see what is "next" at all times.
