Auto BCC when clicking a contact's email address in Zoho

Auto BCC when clicking a contact's email address in Zoho

I'd like to propose a setting where, when you click an email address inside Zoho (not the Send Mail link) it not only composes the email in Outlook (or whatever email client you use) but also auto-BCC's Zoho.  I see it being discussed elsewhere in the forum as far back as 6 years ago - what's the problem with implementing?  This already exists in Batchbook CRM.
