Good new! You can order ProV1x with custom logos using the on-line shopping tool and get a huge selection of alignment marking. Everything from standard lines to several versions of TT alignment markings. Get your own custom number and alignment marking to make your next dozen personalized for you.

Mark, those alignment markings change with each new release of golf balls. That is how they distinguish the year.
What I would suggest is to click on BALLs in the link heading above, Click next on "Prov1", "Customize your golf ball", Under "Logo", Select "Single $5". It will prompt a number of logos including a good selection of alignment markings. Hopefully you will find one that will meet you need. Hakuna matata.

Looks like you can still order them direct through My Titleist. Looking at the web page for Balls, they list V and X available with the new alignment feature. If ordering $170 or more, shipping is free. Should be about 3 dozen to meet that.
