IanCanada ReceiverPI signal routing

Hi all,
I'm looking to add ReceiverPI to my Raspberrypi with Pi2AES board as I need to do digital processing on the Pi side before sending the signal to an external dac.
However, I was not able to find any information if ReceiverPI allows that type of routing.
In short, the signal should always go ReceiverPI - > raspberrypi -> Pi2AES and should never bypass raspberrypi.
Is it achievable?
Which version of ReceiverPI should I get for that? proII or DDC
In addition, I would also prefer automatic coaxial\optical switching on ReceiverPI side based on an input signal.
If auto input switching is not possible can I use monitorpi pro for that?

note: Pi2AES uses HiFiberry Digi+ driver and is a masterclock
Digital audio stream will mostly be 96Khz 24bit or 48Khz 16bit (no dsd audio)

Thank you.
