From Adv. Class Guide pp. 26: "A hunter may teach her companion hunter’s
tricks from the skirmisher ranger archetype (Pathfinder RPG Advanced Player’s Guide 128) instead of standard tricks."
From APG pp. 128: "A ranger can use these tricks a total number of times per day equal to 1/2 his ranger level + his Wisdom modifier."
So two changes are needed to implement this class feature:
1) Hunter's Trick should be an option on the list of tricks for the animal companion. You could list all hunter's tricks in the tricks list, or you could create a drop-down in each hunter's trick row, allowing the user to select which hunter's trick to teach to the companion.
2) If a hunter's trick has been taught to the companion (or even if it's not, if that makes things easier), hunter's tricks uses should be a tracked daily usage resource on the hunter's character sheet.
