More granular privileges

At first glance, the following does not appear to be possible in the version I have installed, but I could be missing something.

I currently have version 8.0.0, Build No. 80234

I am trying to limit more the ability of a user in DC to manage patches. For instance, I would like to create a User-defined role which allows only the following:

Install Patch/Service Pack
On Demand Scanning

When I create a role, I can only define whether that role has Read or Write permissions to a module. Is it possible to get more granular permissions set for a particular user or better yet, a user-defined role?

If this is not possible in the current versions, I would like to request this feature in the next version of DC, if possible.

Thanks in advance!
