Stop Leveling Command

It gets tricky if we're trying to level with INT gear but we're fighting a boss as a team (or solo) and it is not feasible to switch to INT gear in the middle of the battle (either due to getting continuously getting hit by the boss and requiring smoke, or even trickier in the case of multiple boss monsters dying on the same map like at Horntail).

If we could have some kind of toggle command to stop gaining EXP beyond 99.99% and forgoing any EXP until we are able to level up more feasibly at a later time with INT equips, it would make this process much easier. Right now the only way is to pass up on certain bossing opportunities with friends until leveling solo first with INT equips on and that's no fun!
