A way of recording DI and processed signal simultaneously via SPDIF?

EDIT: KPA already does this So no feature request here.

Hi!
I think it would be really useful to have the option of recording a DI and the processed signal at the same time using the SPDIF output, to avoid using the analog outs. I'm not sure if it's possible, but I though in something like using one of the stereo channels for the processed (mono) signal and the other one for the DI track.

Thanks!

Thank you guys!!! I should have checked it before asking.
