Box JavaScript File Picker - Extra data e.g. filesize?

I am using the box file picker found at https://app.box.com/js/static/select.js

 

It only returns a limited set of data about each file: access, id, name, permissions, type, url.

 

Is it possible to have it return more data, such as the filesize and mime type?

 

Filesize is the most important for me.

 

Thanks in advance.
