Select users from Azure AD in the Recipient field of the Send an Email action

After User Directory Lookup is setup, we are offered the ability to select users from Azure AD with the Assign a task to multiple users action. I would like to see this functionality added to the appropriate fields within the Send an Email action. Having to rely on manually typing all the necessary emails out or relying on Azure AD Query Users action is a huge step backwards from what was accomplishable within Nintex for O365.
