AK-47 Iron Beast Special Attack

Hey guys, I was forwarded here from a support thread for my claims. I just wanted to make a suggestion about the AK-47 Iron Beast's special attack. I went into my storage to try and disable the shock charge because it gets a bit annoying when you try to knife a mutant but your shock charge gets in the way and the mutant spawns again in Hero Mode X. When I disabled "Special Attack" and went in game, all it did was disable the knife attack for my AK but the shock charge still worked. I was just wondering if y'all could make it so that you could disable the knife OR disable the shock charge and still have the knife attack working.
