Death Head Crystalis on barter stand (add any category)

[Aceb]

Please, add "any silk cocoon" in barter stand option. When I don't care if I sell Silk cocoon or DHC, I want it to be treat the same way other items are (any meat, any leaf) etc., since if I wanna sell 60 cocoons and I get a few DHC, it's annoying to change everytime the number on barter stand for it to be correct.

Thanks!
