Creating a Sitemap in Relume: Templated Pages Guide

Hi all, I just started using Relume today and am trying to create a sitemap. How am I supposed to handle templated pages? For instance, I have a main pricing guide page with links to individual pricing guide landing pages. Once the user fills out the form, they get redirected to a thank-you page where they can download their PDF content offer. The landing pages and thank-you pages each share the same basic layout template (same sections, just simple variations on the content). It seems like "Change to Page Group" would come in handy here, but that seems to just create a hidden parent page with subpages. Here's how I do it on my manual site-mapping tool, but how do I do it with Relume? Thanks!
