Create New Roles and/or Modify Permissions

[#1]

You can only select roles which has certain permissions, but you cannot assign a certain permission to a role.

It may be more flexible if you can create new roles and add permissions, or modify existing role permissions with UI (something like a spreadsheet format and able to change settings by clicking)

As I have recently posted on the discussion boards, I was extremely disenchanted with Vault when I discovered that user 'permissions' and roles couldn't be customized. I think it's even assumed that software of this nature comes with this functionality. It would behoove AutoDesk to add this feature to Vault.
