Just a quick bit for people who want one NPC to limit break but not another, from what I've seen/tested while running these as my PLD whichever DPS is in the first (top) slot will be the one to LB. So if you want Ryne to use the single target melee LB you need to unselect both DPS and pick Ryne first, then who ever you want as second DPS. Ryne should use the LB in that run now.
