No idea about a BTO. Last fall, I sent a "98 414 (old style neck) for a reset,told my rep where I wanted the action:5 and 3-4 64ths respectively with a minimum of 9/64' saddle out of the bridge between the G and D strings.Put a note between the strings as well. They nailed it.
Guitar sounds and plays fantastic!
Did I get lucky? Probably.
Could Taylor Techs do it again? Yup.
