Nesting categories for related blog posts on a template page

The community member is seeking help with nesting categories for related or other blog posts on a "blog template" page. They are using Finsweet, but the only categories that load for each post are the ones that correlate to the current post, not the related post. In the comments, other community members request a read-only link, and one community member mentions they will restructure the item since they have less than 5 tags per post, so it won't be wrapped in a link block.
