Ability to have Role based editing permission rights at the Questionnaire level

Current Situation:
When creating a new question groups, you have the ability to enable or disable the editing of this questionnaire

Required:
Some questions are only related to accountants,Internal Auditors or even Client Leveling information.
What is needed is to have the ability to add User Roles permissions to these questionnaires, and by this we would add the ability to edit these questions by only certain leveled personnel
