Hey Emptyless,
It sounds like if you have that many items you need to check against, you might want to store all of the HitBox Names you create in an array and when you trigger the Event Receive Hit Box Begin Cursor Over or any other Event for your inventory, have that run through a ForEachLoop on that HitBox namearray and compare the Box Name to each entry, then execute the rest of your code. Depending on what you need it to do, this would potentially make your inventory list more customizable in size and the code burden would be much less (not having to create multiple Switch On nodes with lots of possible entries).
