As far as I can tell you would have to create a participant/follow up action similar to https://rsjazz.wordpress.com/2012/11/30/a-create-approval-work-item-save-participant/ . You would need to do https://rsjazz.wordpress.com/2012/08/02/subscribing-to-a-work-item-using-the-java-api/ or look here https://rsjazz.wordpress.com/2013/01/02/working-with-work-item-attributes/ for subscribing.
