Im not 100% sure what itemizers get priority is, i cant answer that one.
Im at the gym, so the order of operations might be wrong
Get <item> <quantity|all>
Pulls X/all if item
Get <item> <quantity|all> <case|sack|satchel|etc>
Pulls all/X of item from that specific location
If you have 12 eachos in sack and satchel and you do get echo* 12, im not sure which bag it will pull from specifically.
