I have about 70 organizations that we imported with individuals - that will have permissions to view and update information. Is there a way to make sure they can have that permission when we import or bulk edit that information. Right now I am adding permissions one by one.
You can use the API, or the API CSV import GUI. Either way you'll need to have some way of identifying the relationships that need editing.
While I don't recommend running SQL directly against the database, this is one instance where it will be safe - IF you aren't using inherited ("conferred") relationships.
