[Defender] Combine all mails from defender

I've configured Defender to run every night on about 30 different sites. Apparently there's currenlty an unpatched vulnerability in WordPress, which affects every version (link: https://wpvulndb.com/vulnerabilities/9021).

So every night, I'm reveiving around 30 e-mails about this vulnerability on all sites. That's quite annoying, especially since this vulnerability doesn't seem to get patched with great haste, it's been reported over 2 months ago.

Wouldn't it be great if those e-mails could be combined through The Hub?
