I2S Passthrough

Hi,
Can anyone please suggest which MKRZero pins to use for creating an I2S pass-through? I want to connect a SPH0645 I2S Mic and a UDA1334 I2S DAC stereo output simultaneously with MKRZero.
All examples related to I2S based Arduino Sound library only highlights A6 pin of MKRZero as DIN or DOUT. So I was wondering how can it be possible for input and output pcm channels stream on a single pin.
Kindly advice?

best regards,

Niradat.
