In the Summary views for a software update or software update group, make the statistics link through to a list of the machines
In the Software Library summary tab for SUGs and individual updates, make the Statistics pie chart and Compliant, Non-Compliant and Unknown counts link to a dynamic collection of machines in a specific state, similar to the Endpoint Protection monitoring views.

Can I suggest that this statistics reflect the collections this update group were deployed to? Or at least having both statistics. I'm never gonna have 100% on my Software Update Groups as I don't deploy them to all assets (they're servers patches, but have some office patches for instance)
Or link it to a report showing the computer numbers. Same with Windows upgrades.
