Creating a single page documentation / Wiki "include" macro that would assemble (Markdown) pages together

Hi, I would like to have our documentation split to multiple files, say, per-topic.
Then I would like to be able to assemble these into a single wiki page.
Is this possible with GitLab?

The pages syntax is Markdown if that matters.
I would imagine something like:

#Installation of XYZ
Installation is easy:
<#import "Installation"/>
