Unfortunately we don&#x27;t yet have that particular feature... But we definitely want to do something like that in the future.  What are you thinking you&#x27;d use it for (we love to collect information like that for when we do implement the feature).<p>Obviously, using the API you could build a restricted interface on top of fieldbook, but that probably isn&#x27;t what your looking for, I understand :).<p>We&#x27;re also considering doing a mode where you can&#x27;t change any of the metadata (sheets&#x2F;fields) but can add&#x2F;remove&#x2F;change rows.
