Hi Lydiot,
right now one has to select it channel by channel and there is no global view of the related outs or ins. I also suggest that one could select a pre fader output, so you do not have to worry about levels as it is as well not possible, at least to my knowledge, to set all faders to a dedicated level, if the faders are set to different levels. So global overview and selection would make miking with an external console much more comfortable.
