Permission level between Admin and Write

The problem is I can add a project branch restriction to prevent all master branches in all repositories from being altered except for a certain user. Trouble is an admin to any of the repositories can then add a restriction to the branch of that repository for master to allow users to update master within that repository.  I know 'don't give admin' would resolve the issue, but they need admin to add\delete users and their access.  So having a mid level admin (Owner) to allow them to add/remove users to projects and or repositories but not to be able to alter restrictions added by an admin.
