Those ProV1 and ProV1x with the small TT logo by the Titleist script were already produced and boxed in a quantity based on demand. I am pretty sure there is no method for taking completed balls back into the assembly process to add AIM lines. Add the complexity of multiple AIM designs and the demand becomes even less so you would basically create a situation where you were customizing for each individual order, a process that would impact the current assembly and drive up cost. That’s my take on the situation. Since comments here are rarely from Titleist employees, you might head up to New Bedford and take the Ball Plant 3 tour and ask them personally. It’s worth the trip!

The Ball Plant 3 tour is amazing. The process to make golf balls was fascinating and the attention to details throughout the entire process made me wonder why a dozen balls doesn't cost more. If you are in the New Bedford area, it is worth the time to arrange to get a tour. My non-golfing daughter joined me and agreed it was an amazing experience.
