Adding Prev / Next links on Blog post page for a filtered list by category

We have used your custom create content array before with prev / next links and that works great - but I can't seem to find a proper answer in docs or support (old or new) for adding something similar inside a blog post - to go to prev or next post within a filtered list of blog posts (by category).

Do you have any examples of this or has this feature been added to Blog App yet?

Thanks.
