If we want to be absolutely ridiculous and chic about racking balls, then under the cloth we can drill 15 small holes in the slate, and then fill them with retracting steel pegs. The holes under the cloth are present when racking, like a template, and after a break the holes fill and disappear. You can even time it so that the advancement happens a second after the cluster impact, so that the template disappears while the balls are still rolling.
This must have been done before at some point in time. It will not be the future of pool.
