Terminology Changes Affecting Non-Editable Fields

We've renamed Initiatives at the Product level (Epic) which then changes all fields in the Feature record. However, if I'm trying to link to an Initiative at a Product Line - the field in the Feature Record is called something different & users are confused. Same thing happens in reporting. If you are trying to report on Initiative, you have to choose Epic, and then all Initiatives & Epics will populate. I'd love the ability to at least be able to edit the pre-added fields to be a bit more clear to users.
