Looks like I need to create a New System Role Assignment

Problem is, if I go into Site Setting; Security; New Role Assignment, I do not have the ability to create a new system role, I only have the 2 default roles (System Administrator and System User)

I cannot see 'Configure system-level role definitions'

Does anybody know what I am missing here?

Looks like I can edit via SSMS

Connect to the SSRS instance and amend security there

So, the only issue that remains now is how to selectively remove Report Builder

Any thoughts?

Thanks
