Is There A Way to Disable the Automated Update Notices?

I manage a LOT of blogs for clients and business partners, not to mention a handful for myself.

I like the automated security update feature, I really do. But I just received my first notification of a blog being upgraded from 3.7 to 3.7.1. I can see this becoming an annoyance.

It would be great if there were a dashboard to help admins manage these functions. I really don’t want to receive an avalanche of emails about automated security upgrades.

And I do NOT want to have to hack the code on every Website. Nor do I want to have to maintain my own modified images of the WordPress install sets.
