Updates by our clients.

Basically, I would like to allow my clients to be able to auto updates the premium plugins/themes I’ve installed for them. I would not want to log in to my clients’ website and update for them. Neither do I wanted to let my clients able to install any new premium plugins/themes freely using the WPMU DEV Bashboard I’ve setup. How can these be achieved?

Lastly, it would be good if we can make use of our members account in WPMUDEV to select the plugins/themes where we can push it to our respective clients for uses and futures updates.
