I have taken over the administration of a Space from a former employee. I need to change the restrictions of a few hundred pages in the Space. The restrictions are quite varied. Some have just one editor, others are multiple editors, some are only open to viewing. I need to limit the edit access to these pages to just myself and the assigned subject-matter experts. A SME typically only need edit access to a group of pages or sections that have 20-50 topics. How do I change the restrictions of these 20 - 50 topics without opening all of them one at a time?
