Can a templated instance simply list the names of associated pages to include?

[Sauyet, Scott D]

My company's move from hosted to cloud is giving us a chance to clean out some detritus and rethink some beautiful pages full of material that were generated once from a template and are now independent of their templates... and hence hard to maintain consistently.  I've seen Scaffolding Forms & Templates for Confluence and Quick start, but I'm wondering if a slightly different approach is possible.

I'm wondering if I can treat my main pages as aggregations of micro-content from other pages in a structured way.  I'm imagining a template that lays out our three-column view from the names of pages.  So our template would contain the layout and generic common text, and then say, in essence, "the FAQ goes here, the Overview goes there, Training material is over here, and so on."  And then I could configure it with something like: 

{
  "FAQ": "Page name or url of FAQ page for this topic",
  "Overview": "... of overview page ...",
  "Training": "... of training materials page ..."",
  "...": "and so on"
}

Then I could write multiple pages, some of which might point to the same FAQ section, others which might share the Training portion.  But each of these pages would be created simply by declaratively including the appropriate smaller blocks.

Is there something built in or a plugin that works this way?
