Axr4 "Main Out Volume Knob" Sensitivity

Hello. I am an axr4u user on Windows 10.
I want to connect a monitor speaker (adam s2v) that supports AES digital digitally and control the volume using the axr4u’s “MAIN OUT VOLUME knob”.
However, the sensitivity of the knob is low, so I have to turn it about 10 times to adjust it from the top to the bottom of the fader.
I know that the Apollo interface can be pulled up by turning it once.
Is there a way to set the sensitivity of the axr4u “MAIN OUT VOLUME knob”?
Thanks!!
