Does PlayFab expose any API to be able to set or get any custom fields to Player Inventory Items?
Our game currently ties some lightweight information with the instance of different player inventory item, such as "Created On", "New/Seen", "Item Level". This is variable data that could change outside of the base definition of an item created in a catalog.
I don't see anything in the API, my suspicion is no, as it could potentially add an unbound cost to the storage of a single inventory item instance.
