Red Hat Certificate System, how to customize attributes in subject DN, e.g. change "E" into "emailAddress"

Issue

How to create a certificate's subject DN with custom LDAP attributes?
For example, how do you change the "E" field of the subjectname in the user certificate to "emailAddress"?
A user was issued a certificate, and it needs to change from:

SubjectName: UID=first.last,E=first.last@example.com,CN=J Test3,O=example.com

To:

SubjectName: UID=first.last,emailAddress=first.last@example.com,CN=J Test3,O=example.com
