Roon as an output channel for other sources? Ugh, but maybe

My general question is whether Roon can take the the digital output of an external device (such as digital out from a CD transport) and run DSP/convolution on it?

If so, how does one set this up?

Specifically I am trying to get Roon to “see” a PS Audio NuWave Phono Converter. This device can digitise vinyl playback on the fly and send it to my mac mini.
Roon server runs on the same mac mini

I’d love to be able to run DSP on this signal (then I can could have room correction on my vinyl as well :slight_smile: )
