Make Notes, available as a relationship custom field

We use notes to capture information related to the EPIC. While there are other custom fields that can be added natively to an EPICS's layout Notes is not one. The only way I've seen to attach a NOTE to an EPIC is making it RELATED. The issue with that is prominence. We have non-Dev/Product folks looking for the notes - burying it in the related section is a friction point. Making it a field on the Overview page would improve usage and awareness.
