Duplicating Pre-existing items

I always seem to come across this issue where the GM doesn’t realize a named item exist in the World Building tab and decides to create a brand new item with the same name as the item I am referencing. Example, Input: [Jim goes and orders a ‘SpiceBurger’ from the menu] Output: [Jim walks over and gets his ‘TheSpiceBurger‘ from the counter].
This also is related to the general issue of the GM not using the items existing in the items tab as general objects that can exist in the world. I would like to see the GM talk more about the ‘SpiceBurger’ ads on the streets of the Cyberpunk city, stuff like that.
