They could always add an option to pick which bag (sack, satchel, inventory) you want loot pool items to fall in to; or better yet have it automatically pick in an order so shuffling isn't needed (items fall into inventory, if full, fall into satchel, if full, fall into sack, if full, oh well). The only problem here is if someone is running around with 1 slot open and wants to get a pop item to pop an NM, and to that I say, allow us to use all 3 of the bags we carry in the same fashion as our inventory, allow trades from, synthesis from, and preferably, consumption and equipping from our sack, satchel and inventory.
