Option to exclude out of date plug-ins from mail notifications

Hello, this may already be possible but I can’t see how. I run plug-in updates once a week for all of my websites, so I don’t consider a new version for a plug-in becoming available as a “critical” issue. The problem is that I am missing genuinely critical issues because there is so much noise in the email notifications about plug-in updates. Is there any way to exclude these from the email notifications? Thank you.
