Is there a way to add the Dependent Name in the BEN_DOCUMENT_APPROVAL alert?

Summary:

We are using the "Document approved or rejected" (BEN_DOCUMENT_APPROVAL) event alert for Open Enrollment this year as we're now requiring proof for dependents. Our benefits team would like to include the dependent name on the approval & rejection alerts, but I've tried everything that Google has suggested and nothing works. I just get "null".
