No, we don't currently have such a feature; off the top of my head, I'd be concerned that the maintenance demands of keeping such a feature current across different releases of OJS would probably outweigh the benefits. I'd suggest working your way through the database layout starting with the "journals" table and seeing what links to it by journal_id; you should be able to work outwards from there to determine what records pertain to a specific journal and sync them via some custom code.
If we see enough demand for this feature, I'd say we'll consider adding it -- but it'll be a significant amount of code.
