Aside from the quantity tracker, is there any way to set this up so that you can restore the usage of each power on an individual basis? I ask because I'm trying to set up a way to use the D&D 3.5 book Tome of Battle. It gives you a bunch of per-encounter abilities, but each class has a way to regain the usage of one or more mid-combat (worse yet, one regains a random one each turn). So for example, a character may have used up the powers called Burning Blade and Shadow Strike , and when they trigger the recharge ability, they can choose one of them to regain the use of, but not the other (this being in addition to it recharging at the end of each encounter).
