Discourse Automation Plugin might help? It has a script to add a tag, so maybe it can help. Or maybe you’d need to do something with the API to move the topics, or have a plugin that used add_model_callback(Topic, :after_create) to identify the new topics from your site and re-tagged them.
So it would be one embed for all documentation pages, but embeds in different docs would, ideally, have different tags. For example, the following docs structure:
I think I understand. If you want them tagged, you’d need to do that with the automation plugin or a custom plugin as I suggested before. I guess you’d get the tag by parsing the URL of the place it’s embedded.
