when I choose the action "Send Email" from the Gmail app and make a connection, it will only allow me to send the email from the primary address. It does NOT allow me to send the email from addresses that are aliases. Why? This is the only gmail app I've seen that does not have functionality built in to accommodate sending emails from alias accounts. Please enable functionality to do so. Maybe create another field that says "senders address" and validate against primary to see if it is an alias.
