Added new command as /bottle store [exp/levelL/max] which will put defined amount of exp into bottle. You can ether define particular exp amount (357), define level amount (12L) or use max to put everything you have into one bottle. Amount put into bottle will directly depend on your xpEarn and xpCost settings, so in case you have xpCost set to 10 and xpEarn set to 9, then trying to store 1000 exp you will loose 1000 but you will only store 900 due to exchange price.
