It has happened to us that duplicating a job has resulted in the same Meta description and thus showing erroneous information in our previews across platforms.

A good way to avoid this type of inconsistencies could be to have a "preview"/"approval" step whereby all the fields related (including settings) to a position would be summarized (some even "demonstrated" such as Meta Description.

Further idea: This could be one step towards implementing multi-step approval processes sometime in the future.
