Is there any way to customize the roles available in the Enterprise Manager? I want some users to be able to run backups and see backup jobs, but only for the servers that they have access to. If I make a user a Restore Operator, they only see "their" VMs, but can only perform restores and have no visibility into the status of the backup job. However, if I make the user a Portal User, they can see the all of the backup jobs, even though I've limited their scope to a specific subset of servers. Is there any way to create a middle ground?
