Accept Caption When Uploading From File and Drag and Drop

[benakkiplagat]

We want to upload an image with a custom caption and an image at the same time.
As a result, we ask that you allow this section (attached) to output caption together with the url in the normal manner.

• How we want it....
  {
  "type" : "image",
  "data" : {
  "file": {
  "url" : "https://www.tesla.com/tesla_theme/assets/img/_vehicle_redesign/roadster_and_semi/roadster/hero.jpg"
  },
  "caption" : "Roadster // tesla.com",
  "withBorder" : false,
  "withBackground" : false,
  "stretched" : true
  }
  }

Regards.
