Creating Assignments that students will access several times via Google Docs

[mrnorthouse]

I'm looking to add a Google Doc to an assignment and then have students access that google document several times throughout the entirety of the school year. I'm thinking I'll be able to reuse the same assignment several times and have the students turn it in three times, but I'm wondering if each time they access that assignment in a different module if Canvas automatically create another copy for the student? I'm hoping that students will be able to access the same document. Thanks for any insights.
