Student Registers Permission - Child Protection Registers/Tighten Security

We are using Flags in Registers Module for the Child protection Registers. However, we wanted to hide the sensitive information to staff. We hope that there would be feature in iSAMS to modify the permissions per elements in Registers.

Because as of the moment, if we set read access in Register permissions, it will allow the staff to see the whole details in Student Registers Module and we hope to show only the FLAG element.

Example Staff A with Full Access to Student Registers Module to edit and modify SEN Registers , then we want to give Staff A Read access in another register called Child Protection Registers however we want only to show the flag and not the whole details because someone else is assigned to CP Registers. Then the rest of all staff should only see the CP flag.
