More conveniant way to use Exp Cards

How about having an option to select how many exp cards to use on a single monster instead of repeatedly pressing "continue".This would be much faster.

+1 for the use all button. It is quicker and simpler (skip a step where you have to enter an amount). Player usually either use a few or all to boost to level 50 quickly anyway.

Of course the use all button will either use up to 50 cards in that stack or auto stop when the monster hits level 50.
