Quests and Google Docs

I created a simple quest to try out the assignments feature. When writing my story and assigning the task, I attached some Google documents. It would appear that when I do it that way, each student gains access to the same document. I'm assuming View privileges only? 

Is there a way that one could create a copy of that document for each student, similar to Google Classroom? Or is that best done through the Assignments tab, and have the students create their own document and attach it?
