The use-case here is to create a collection of strings (for example Users) using Value Supplier.
Currently users are able to create a number or a string for example, but there's no way to create a collection like below:
["User1", "User2" "User3"]
Adding the list creator key to Value Supplier will allow users to create the collection.
