You can sync (using the ‘clash status sync’ option) a custom status from BIM Track to Navisworks in such a way that it translates as a ‘Reviewed' clash in Navisworks.
Creating a custom attribute as only an informal value. This can be changed in the Attributes section of the Project Settings page by activating the Set as default button right under the custom status that you created.
Check if this is compatible with the workflow, since it removes the ‘open’ status will not be default one. Even after changing the default status, any issue with the open status will still be recognized in Navisworks as a ‘Reviewed’ clash (when applying the sync).
