If I save a story under no certain topic, the "link me"-perma-link will be generated as .../[creationdate]/#####. Whereas if I save a story under a topic, the perma-link will automatically created as .../topics/[topicname]/#####, but the story remains also parallely available under .../[creationdate]/#####.

Question: Is it posible to influence the way a perma-link is created? I think of a setting that always chooses the [creationdate]-version as perma-link, even if a story is related to a topic.

Background: subsequent changes of topic names or story classifications ("topification"?) turn perma-links into dead links.
