JSM - Ability to change email "from address" in automation emails

When sending emails from automation rules, we can currently change the name of the sender, but not the "from address", which remains greyed out, and is "no-reply@automation.atlassian.com. 

This poses an issue for several reasons : 

• the customer can actually reply to the email that is sent, and this is something that we can customise so that the customer can get in touch with us if needed.
• given that the address is the same across all Atlassian instances, anyone can set up an automation email, which poses a security risk. 
• we are using a custom domain for all the other notifications to clients set up in the portal, so the automation emails we have set up being sent from another email juxtapose the custom domain, and are potentially blocked by our clients' email filters.
