Embed 3rd-Party Disqus Comment Script in RH Masterpage Footer: PAGE_URL + PAGE_IDENTIFIER Variables?

Environment

• RoboHelp 2019 (new, update 12)
• Generating HTML5 Frameless output

Goal

• Provide comments section at the bottom of each topic. Specifically, provide a Disqus (disqus.com) commenting section/functionality at the bottom of each of my RoboHelp topics, by inserting the Disqus service's code in the footer of my RoboHelp masterpages.

Problem

• For each topic (webpage) the Disqus script in the footer of each topic requires 2 unique pieces of information: the PAGE_URL and a PAGE_IDENTIFIER. Actual script provided below, additional info/details from Disqus here: https://help.disqus.com/en/articles/1717084-javascript-configuration-variables
• Hardcoding/manually entering this information for every topic would be both an implementation and a maintenance nightmare.

var disqus_config = function () {
this.page.url = PAGE_URL; // Replace PAGE_URL with your page's canonical URL variable
this.page.identifier = PAGE_IDENTIFIER; // Replace PAGE_IDENTIFIER with your page's unique identifier variable

The Big Ask

• Are there RoboHelp or (more likely) agnostic, standalone scripts (Java, PHP, etc.) that could generate and serve up this information? WordPress and other popular web development and hosting solutions apparently can do something similar via their custom-developed Disqus plugins. That might be easier for them since they're also the hosting service provider.

This may be a candidate for a feature/enhancement request, but I thought I'd see if anyone in the community had a solution first.
