That's something else you couldn't do in a Chicagoland election. You could take a big stack of ballots to a booth and fill them out and file them, but at the end of the day when the polls closed, those ballots would have to match the number of pollbook registrations that used paper ballots. You can't just make those up; you can't vote provisionally with paper ballots, so all those ballots would require pollbook registrations for registered voters.
