Type reference as a custom field

[Ojay]

Hey @dennispassway - was just going over a few things Media Library with the hope of adding a reference field to the media library via the Custom Fields config. I tried with the below but to no avail... any ideas on implementing this or is this something that'll be part of this enhancement??

Thanks!

  "theme": "light",
  "themeChanges": {},
  "customFields": [
    {
      "label": "Photographer",
      "name": "photo_photographer",
      "title": "Photographer",
      "type": "reference",
      "to": [{ "type": "photographer" }]
    }
  ]
}
