Hello Chethan,
Sorry, no support today for that kind of field, maybe you can make a small working example, starting with a master and validation, and from there I would try to translate. Let me know if you get the time to get into it, is a very interesting field type.
As of today supported field types (document and image will change in 6.1 final), are showed in the image following.
Saludos, Jack.
