If there were some way to iterate through the actions (ref. the sort of thing I was suggesting broadly here), and get the file and/or URL, then I believe it would be possible to roll your own export for any platform you could connect to - Dropbox, Google Drive, One Drive, etc. If you had the URL you could even build a web page to archive to, push it out as links in an Evernote note, a nice little Markdown based e-mail; and so on.
Some sort of advancement on the find action to allow you to return an array of actions. Use of wildcards or search operators to narrow it. Maybe action groups too.
In-built is great, but opening it up I think would be better. This is probably an edge case based on iCloud access restriction, but personally I think focussing on the actions rather than a feature will allow the community to build a solution for that and so much more that probably hasn’t even been conceived of yet.
