Hello! We need our Heads of Schools to have ACT AS USER access. However, we can only give them access to sub-accounts since we do not want them to have full access to our Board Room course. We created sub-accounts and placed them as admin in those. Is there a way to either limit viewing of a course from somebody with full admin access to the root account (seems unlikely), or is there somehow a potential for allowing them to act as user in the sub-accounts?
