As a business user I want to add dynamic fields to the email subject of emails sent by Configured Commerce.
Specifically, the Subject field of an Email List (Marketing / Email Lists / <selected list>
Example: OrderConfirmation
Subject: Order Confirmation: [[Model.OrderNumber]]
Result: "Order Confirmation: WEB001117"
With DotLiquid evaluation of the subject, we could even add logic like:
Subject: Order Confirmation: [[Model.OrderNumber]] [% if Model.CustomerPO != null and Model.CustomerPO != "" -%] (PO: [[Model.CustomerPO]] [% endif -%]
Result: "Order Confirmation: WEB001117 (PO: 12345"
if the order had a PO assigned.
The Model used for evaluation should be the same as for the body.
