Imported Assignments that use Google Assignments: Have to be re-built in your new course

[jchaomignano]

I'm an administrator and an ELA teacher in my school shared with me that after we imported course content from her previous course, for each Assignment that used Google Assignments LTI as the external tool, she had to do this:

1. Edit the Assignment to clear out the External Tool settings (ie. set it to No Submission)
2. Save this.
3. Edit the Assignment to add the External Tool setting of Google Assignments
4. Go through the whole rigamarole of setting up the Google Assignment (finding the document, creating a copy, setting grading preference)
5. Save it again. 

For every single Assignment, which already has all the information set up -- There must be an easier way to this... Are we missing something?
