Absolutely Disallow Technician Access

Since Level doesn't have the ability to dish out permissions to end users and/or business owners that want access to devices we need to add a user "tech" and assign specific permissions. When speaking to a business owner they asked why they had servers in there view that they didn't know about. Come to find out they have access to the root of the organization and whatever device group they are assigned. I'd like to see the ability to not allow that and define only specific folder access including the root device group directory.
