Custom learning role based on the seeded learning specialist role

Content

We need to create few custom roles based on the seeded learning specialist role

For example custom role  : learning design specialist

This role has following limitations.

 

Maintain Content          Y

Maintain Instructors      N

Maintain Classrooms       N

Maintain Training Suppliers  N

 

I tried to do it by editing the seeded role but it seems like not working after assigning  to the user.

Appreciate your ideas to achieve this
