Hi @john-olav,
Welcome to the forum, and thanks for considering us!
Unfortunately, bulk editing is something we currently do not support in the CMS itself. There is an open feature request for this: Bulk search and edit feature
Right now, the only way to bulk edit many records at once is to use our Content Management API and make a sequence of calls:
- List records: https://www.datocms.com/docs/content-management-api/resources/item/instances
- And then update one record at a time: https://www.datocms.com/docs/content-management-api/resources/item/update
Sorry about that!
