Something they did on Live to help reduce confusion for combines like this is they would apply a specific slot to the symbol or item (for example Poison Symbols would be:
MAGIC ITEM NODROP
Weight: 0 Size: TINY
Slot: CHEST
Item type: Gems
Classes: All classes
Races: All races, Froglok, Vah Shir, Iksar, Gnome, Halfling, Ogre, Troll, Dwarf, Half Elf, Dark Elf, High Elf, Wood Elf, Erudite, Barbarian, Human)
This way we can easily determine during the actual kills which symbol goes to which slot. If it's too much of an issue thats fine it's not a huge deal but it would make things a little less confusing while distributing loot
