Clicking on this link will download a copy of the enhanced Google Sheet. There are instructions. Basically, you can carefully edit the tabs representing the conferences and the teams. If you use the Team ID from the Teams file, the application will generate a schedule output that you can put into a CSV and load in. Each year, you can update for conference realignment, for how the teams finished the year before, and the scheduler will create a new schedule for the next year.
Feel free to leave feedback here, although this is a labor of love and not my day job nor my brother's day job, so it might take a bit to implement any changes.
Good luck!
