Insert to storage NPC

[c2greentea]

I need an NPC when clicked it will ask what account ID, item ID and quantity to insert to the respective account's storage. OR a premade one where once clicked, it will just ask for account ID and automatically the list of items shall be given to their storage. Anyone pls?

trust is there are none cmd in the main repo to insert an item in the storage of a player online, and none command to check if the player online opened his storage. Also it's not efficient by sql, and there is a possibility to exceed the max storage. The best way should be a source mod, "additemstorage"
