Global Models data security

Summary: How can data security be enforced on the global models?

Content (required): Our HR Admins all have access to global models, but should only be able to model within their span of control. However, it seems they can model (and see the eligible salary) for everybody within the global models. Is there any way to make sure only people/assignments within their span of control are included?
