Describe the feature/addition!

Trades don't exactly have anything that identifies them, but if you could remove a trade from the output ItemStack that would be much preferred for my use case than removing all trades of a certain level. I guess this would still remove all trades with that output stack, but this is a more accurate way than what is currently available.

Why would like to see this feature/addition?

Removing all trades of a certain level removes some trades that I don't actually want to remove. I can add them back but I think it would be cleaner if you could specify the output ItemStack for more fine-grained control.

There is already a way to remove stuff by a TradeFilter but it's not fully fleshed out. There are examples in the discord for this, you can lookup there for more information.
