To discuss the idea a bit further, I can sort of imagine a convenient system where the MU commander can also use the CO account to purchase supplies off the market. The supplies can be stored in the MU storage area, and then anyone in the MU can use a certain amount of supplies per day. The amount can be chosen by the commander, with no need to individually transfer items to each player, they just get used up when the MU member fights and eats, up to the point where they reach their daily limit and resume spending supplies from their own inventory. There can be a log to record all transactions: who is using their daily supplies, and who is donating them, and who is using the MU account to buy from the market (including price/volume/seller details). The full log is very important to deter corruption, especially with state MU.
