How to increase sensitivity of pitch bend on jog wheels of controller -- DDJ400 (rekordbox)?

With DDJ400 the pitch bend is so insensitive that I could basically spin them like I am going to die and they only nudge slightly. How can I increase this outer platter sensitivity so that it can be more similar to DVS? I don't mean the platter sensitivity in terms of vinyl mode and scratching, I just mean the outside so that the pitch bend is occurring at greater increments than currently, it is.
