Ability to mask a cc'd email using CEMT's in Adobe Sign

[#1]

Description - To have the ability to mask a cc'd email address on the email notification that the external signer receives 

Why is this feature important to you - I have multiple customers with this specific use case and would like to offer it as workaround solution for masking email addresses so it's not viewable by external signers. In this scenario, the email address we're trying to mask is the vice president of the company and it's important that their email address not be shared.
