Adding items to containers in Areas?

This adds an item to a creature
COPY_EXISTING_REGEXP GLOB ~^_?hlkoshi\.cre$~ ~override~
REPLACE_CRE_ITEM ~katana4~ #0 #0 #0 ~NONE~ ~SHIELD~ EQUIP

This adds an item to a store
COPY_EXISTING ~wmart1.sto~ ~override/wmart1.sto~
ADD_STORE_ITEM ~Katana3~ AFTER ~wastaff~ #1 #0 #0 ~IDENTIFIED~ #1

I'm trying to add an item to the container (pool 1) of area AR0310.ARE in BG2EE, how would I script this via a .tp2 file?
