Toggle crouch/Hold to slide

I want to use "C" key as my toggle crouch key but I don't like having to double tap it to slide I want to be able to hold it to slide thus keeping its normal functionality with crouch sprinting and sliding in the same way that double tapping it is contextual.

In the settings menu, you guys misspelled "crouch" in the infantry control settings > movement > crouch slide description > "CROUCH HOLD: Crouh (Hold) only"

Not being able to access the settings while in the firing range is a massive headache....

Also being able to use all of your kit in there would be nice too.
