Learning E-Mail Notifications for managers

Summary:

We currently have an alert set up to send an email notification to a learner when learning is approaching the due date.

Using a very similar set up to the one that Brandon Kwong-Oracle outlined in a response to https://community.oracle.com/customerconnect/discussion/comment/658748

We've now been asked by the business if a duplicate of it can also be sent to the line manager of the employee receiving the alert.

Within the learnerLearningRecords resource is there an manager equivalent of ${AlertUtils.person(learnerLearningRecords.assignedToId).WorkEmail} to use?

Or do we need to go about this a different way?
