Roon DSD upsampling works with DSP EQ, but not with DSP volume control!

For some reason, Roon tries to perform volume DSP after DSD conversion, but the parametric EQ function is performed prior to DSD conversion.
I have been messing around with Roon's parametric EQ and I think it will very useful. I am planning to get a mic and software to measure in-room response.
The top graph is a FR response curve for the Magnepan MMG that was supposedly provided by Wendell Diller of Magnepan. Just for fun (I realize the in-room response will be much different), I tried a curve to smooth out the troughs and it sounds really good.
