Fine-tuning read permissions for role

Is there a way to give a role read permissions on a collection type, ONLY when viewing it as a relation within another collection type? For example, I want to give a role permissions to view authors such that I can add an author relation on the article collection type, and the user can then view a dropdown with a list of all the authors and see their names, rather than just their IDs. But if I give this role full read permissions on authors, that role then gets access to the Authors collection type in the content manager menu too, which I would like to be hidden.
