Fusion HCM Routing Workflow Emails

Summary

Trying to determine how to customize emails used in Workflow and Routing

Content

Hello, I am working on Workflow and Routing in Oracle Fusion HCM using the "Manage Approval Transactions" task.  There are email notifications sent to the originators and recipients of the routes.  For example, when the task "Update Marital Status and Change Address" is routed, an email is sent to the person (or role) who needs to approve the update.  How can these emails be customized so the email body is not so cryptic?  How can the subject line be changed?  See the attached screenshot of an email.
