Create a modular page with pages from other folders

We are starting a project to build rich documentation dedicated to the Web solution we are providing. We often have to create and maintain content that is replicated in different tutorials. I was wondering if modular pages could be made of pages from different folders than its own?
Thank you!

I think the page-inject plugin might make your job With this plugin you are able to access content from other pages with a link in your markdown Editor.

Thanks a lot!
