New-ManagementRole parameters

I need to give all users more rights to modify their personal information.

where can i find the parameters so i know what is possible to assign to them?

They would like to modify  - Title,Company,Manager Name,Manager Middle Initial,Manager Last Name

if i create a new role

New-ManagementRole -Parent "MyContactInformation" -Name "CustomInformation"

what do i do next?

right now it has the same right as the mycontactinformation role. Need to add the others listed above.

i would like to assign to one user first to test but then globally.

thanks
