Nity Stat Editor

this is the line in Nity's stat editor I am trying to make it when Me and ppl in the Menu are using the Stat editor it also changes there Wins and Losses and also kills with there favorite weapon. But you can't change kills with your favorite weapon I am pretty sure I would be able to change the amount of kills with a certain weapon. I would appreciate your help. I have skype and team viewer so if u would like to help me over those channels i am cool with that
