ATP Anti Phishing Policy missing common name spellings

Hello, 

Using ATP anti phishing polices to protect our CEO/CFO/COO. 

When an email comes from display names that have alternate spellings of the name ATP Anti Phishing is failing to quarantine the messages. 

Example - spoof of Matt.Ceo@fakedomain.com <Matt CEO> will get quarantined.

Spoof of same user: matthew.ceo@fakedomain.com <Matthew CEO> will be delivered to inbox.

Any way to make it better?
