satellite 6.2: How to apply updates/errata's to a client system automatically?

I want automatically push updates via katello weekly or monthly so I can have scheduled updates. I currently push updates manually by going to Hosts>Host Collections>Collection_Name>Collection Actions>Package Installation, Removal, and Update>Update all packages.

If this is possible, can I select only the critical updates?
