Can I record digital returns back into a DAW?

For mixing purposes, I like to send each chael from an already recorded session back to my Studio Live 16.4.2 AI so I can mix using the board. Obviously the digital inputs must be activated for each chael. I was able to get signal back into the board. BUT, no per chael EQ would make an audible difference and I wasn't able to send the signal back to the daw to basically re-record each track through the board. I could assign the chaels to subgroups and then re-record the subgroups, but I really want to re-record each chael separately.

Is this possible?

This is with a Mac Book Pro and Studio One 3 Professional
