No shortcut to cure. As BattleGnome pointed out, curing soap is more than just the evaporation of liquids. It a chemical change taking place, which takes time. And nothing can take it's place.
It will get harder faster in hot arid climates, but will not cure faster. It will still take the 4-6 weeks standard, to cure. If you are using a high percentage of Olive Oil, or making a salt bar, the cure (to get the best bar) can be even significantly longer.
