I could get into why this is as it is and why I'm fairly unwilling to
bend on it but the short answer is, Option II is there to do this.

Yep. (Pages 42-48 of the manual attempt to explain the spreadsheet)
Also searching for files that end in .spreadsheet should popup some
published examples that are out there.

Most people have gone this way.
