Although I don’t quite know how to do it, I imagine that if you standardized where you added the tags, etc, it would be possible to create a Templater script to do this.
I was trying to figure out how to do something similar and received some hopeful suggestions, but no Templater solution. On the other hand, I was able to create a little AutoHotKey macros to save some time. Here’s the link if you want to check it out: Copy text and block link to clipboard
You might consider checking out Note Refactor plugin, although it probably will be unable to accomplish what you want.
Generally speaking I’d highlight the excerpt to extract, trigger the template and extract the extra information from the frontmatter, create the new file with all info, and leave a link in the current file to the newly created file.
