Edit Roles in OJS 3

Hi!

Our journal is one of several that is hosted by our institution. A user has an account on multiple journals. I want to make this person a Section Editor, but when I click to edit his profile (thereby his role), it tells me I have to be an administrator over all of the accounts. Is there any workaround so that I can modify his role in our journal?

Working off of OJS 3.

Thanks!
