DJM-S9 Utility phono attenuation control

Hello, 

Where possible, I like to have my trim pots at 12o'clock, that ends up being a bit too hot when playing majority of my vinyl on the S9. It would be great to have some control of the phono input gains via the utility. 

The Rane 62 utility has this function. I doubt it's a trademarked setting.

Many thanks.
