individual button sensitivity

[accuvaccu]

I'm playing Ace Combat and I need to set the R stick and the square button to half sensitivity only but I only see a general option in settings. The older versions had this option and I'm hoping the new ones do too. Am I dumb and can't find it or did they remove this feature?

Many thanks my friend!
