You can let the speed creep up a bit in PATH on the way down, but then you'll definitely need speedbrake for the deceleration point just above 10,000. So TAI at 15,000 will flatten the descent and allow the thrust to go effectively below idle (as long as you haven't actually got the TAI on!!) You'll still need to tweak the levers though to keep the correct speed.
Or just use the brakes when you need them 😉
