As an additional example: Medium achieves this with Publications.
I have cross-posted to Medium, dev.to, and Hashnode, but Hashnode is the one that doesn't provide the functionality being requested in this feature request. Example use cases include wanting to have an official company/community/product blog, where the authors may change over time or have multiple authors with permissions to post to it. Though, at the same time, still crediting the original authors and for those posts to show up on their personal dashboards/feeds and profiles.
Three examples of cross-posting with canonical URLs, including with Hashnode without the requested feature:
