[Economy] How to properly stack instances of items in player inventory?

[ByteflowX1]

I’m making a card game where players need to collect cards and have the ability to level up the card (similar to Clash Royale). I’ve created an Economy Inventory Item for each card and also a Currency. The game will have around 50 cards.

My question is how can I stack cards instead of creating a new instance in Player Inventory each time? Or is there perhaps a better approach to implementing this?

I’ve installed Economy Package 3.4.1 and opened the InventoriesUISample scene. It seems there is an option to stack items if I specify the (Optional) Player’s Inventory Item ID, but I’m getting an error (see screenshot).

The only way is to somehow check if I already have that card in my inventory and update the counter in the instance data with UpdatePlayersInventoryItemAsync?

Also, why is there no ‘delete’ button for items in the inventory? I have to delete the entire player.
