Teh email layout is used within the email template. So have that set-up. What i am looking to do is have a dynamic first line on the beginning of the email above the header so it appears in the email preview. I am hoping there is a variable or something we can use to do that similar to how you insert ${notification:body}

What is in red text in the first image below is what I want to add to the email layout/template but make dynamic. This is what shows in the email preview (pointed at in green in the second image)
