Sending an email out from different email addresses

Hi, I am trying to create an email that will go out to our clients as a reminder when an appointment is set up. Ideally I want this email to look like it has come from the user that they have been dealing with.

Is there a way to has custom From email details? I previously had this set up in TA v4 using the "Send Via" option in the Send an Email Triggered Action but there doesnt seem to be a similar setting in V5

Thanks
Conor
