Happy holidays - Roles with the compass

Hello everyone, 
With my team, we are using 3DX through a challenge, but some members of the teams have some roles like Engineering Expert (we are looking for the composites apps) and other members don't have this roles. Is there any way to add this roles to other members ?
Have a nice day and enjoy Christmas ! 
Best
