Send notification including output documents from ESS job

We have an integration that runs Import Orders. We are finding the job status is 'Succeeded', however sometimes a PDF is created detailing orders that have failed to load. We need a simply way to send that PDF to the business. Does anyone know how to do this? If I look at Notifications settings on the job itself, you can only send notification based on the ESS job status but the documents outputted aren't included.
