In Google Classroom I can assign topics to my assignments. When I create an assignment via Kami, this is not an option. So then you have to go into the GC assignment anyway to indicate the topic. It would save a step to have this option in the Kami assignment creator.
Unfortunately the API that Google provides for Google Classroom doesn’t support assigning topics to assignments at the moment, so we are unable to add this to Kami. We’ve let them know that it would be a useful addition though, so hopefully they will implement it and then we will be able to add this to Kami.
