Within the Gradebook, you can upload grade changes to existing assignments or create new assignments by using a CSV file.
If you don't want to create a new CSV file, you can always download the CSV from Canvas Gradebook, change it, and re-upload the same file with the changes you made. The changes will appear in Canvas once you re-upload the CSV file.
