We've added a new type of order automation rule that automatically parses the value of a specified order attribute, and applies that attribute's value as the delivery date for any order containing a matching attribute. Route planners can customize which order attribute to automate from, and which international date format to parse the delivery date under, by using the text box and dropdown when configuring this rule.
Enable and configure order automation rules from your EasyRoutes Settings > General tab, within the Advanced automation section shown above.
