How to include a page in index.inc.php

I have found a lot of questions on the forum darting around the topic and everybody settling on regularly hacking the template files to achieve it.

So far, unable to find any litecart functions to correctly/efficiently achieve the following...

using the admin console, add an information page and call it home. This page is to be included on the home page (index.inc.php)

so on index.inc.php you would use something like<?php include 'home.php'; ?> (obviously this wouldn't work as it is not an actual page, it is a database object.

Therefore - in keeping within Litecart functions, I thought there would be a function that went something like...
<?php echo $page_id['1']; ?>
However I can't find any such function. https://www.litecart.net/cs/wiki/functions

Any one have any clues?

(P.S. reasons people may want something crazy like this... so the person operating the admin panel can change their own data on the homepage)

as an alternative, maybe you could use something like this addon: https://www.litecart.net/en/addons/770/intro-frontpage
It is editable in the admin and it is included on the frontpage
Note: (content is saved in a .json file, so not in the DB)

In php it's..

include 'path/to/script.php'; // Executes code

or

echo file_get_contents('path/to/document.html'); // Outputs the contents of the file
