Is is possible to only allow open up certain data sets within a BigQuery project to Connected Sheets? We have a project with multiple data sets, some with PII and some without. I don't want it to be possible to put PII data into Google Sheets (of course people can always copy and paste, but people are trained not to do that!), for GDPR reasons. What would be great would be if Connected Sheets could be turned on or off for individual data sets.
