Import feature request Ability to specify default for fields

Ideally it would be possible to add a widget to MapField page on imports to store defaults - this gets us away from saying 'add a another column to your spreadsheet for (e.g) Financial Type and here is a video to watch to learn how to fill-down'

This is primarily a UI issue -injecting the widget - which could be angular - once saved to the user Job it would be easy to handle
