Next/Prev buttons inc. child?

We’re trying out wedocs which is great so far, but when you have nested docs, the prev/next buttons only include the parent pages. I.e.:

• Modules

• Module topic 1
• Module topic 2
• Module topic 3

• Events

• Events topic 1
• Events topic 2
• Events topic 3

So if you’re in Modules, the next button will say ‘Events’, whereas we went the next button to say ‘Module Topic 1’.

Any help much appreciated.
