Federated Search crawlers should include a way to include external crawled content in the section, article pages

Feature Request Summary: 

The configuration options for Federated Search crawlers should include a way to include external crawled content in the section, article pages as related items similar to as is done today for other guide content.

Description/Use Cases: 

We rely heavily on federated search from zendesk guide as it integrates our booking system content using crawlers. However, the usefulness is limited as those external content items only show up in the search results not in context to related articles where keyword, tags are similar.

Business impact of limitation or missing feature:

Currently, the crawler results are only in the search results so it difficult for users reading an article to navigate from an article or section directly to related crawler content - they would have to back to search, conduct a search and then select an appropriate external link. This is simply not best practice from a user journey perspective.
