Powerpoint 2016 - Inserting automatic titles/headers based on section name

Basically, converting Steve Rindsberg's comment into an answer:

PowerPoint has no function like this built-in.

However, like most Office products, PowerPoint does have the very powerful VBA macro engine, which would certainly be capable of doing this.

Your macro would have to capture the Section name based on whatever parameters you choose to use to mark that, and then it could place that information anywhere you please within subsequent slides.

Because slides are more about visual layout than programmatic auto-creation, this is something you'd have to build yourself.

But, also like Steve Rindsberg noted: Get something started and as you come upon questions, our programming sister site StackOverflow would be a great place to ask them.
