Signals Routing issues

As you said there’s only one stereo channel (yes I want to record drum machine and guitar), there are not separate aux in and main in recording channels. If I set the aux in as a recording source as well as the main ins then they will be merged on the recorded track on Aeros.
Do you think it’s going to upgrade? I wrote on an other thread to make a real routing page with panoramic and capabilities to record track 1 with aux (drum for me) and track 2 with main ins (guitar on left channel).

That’s an idea because at the moment there are too many restrictions.
