Bookmarking threads so they always default to the last page or first unread post?

self explanatory title. Is there a code I can stick at the end of the thread url to force it to go to either the first unread post or the final post in the thread?

If you add /unread at the end it brings you to the first unread post. No clue if there's something similar for last post.
