What's the problem? Only in the routing of the channels ?
Then it would be good to deliver a good problem description that contains
- what you want to achive
- what fails exactly
- the relevant information to be able to to understand / reproduce your issue.
One idea upfront in terms of routing: configuring routing in mixer view (in submix mode) is maybe easier for you.
Because all that you need to do is for every HW output
1. to click on this particular HW output and then
2. raise fader of the inputs (HW inputs, SW playback channels) that you want to hear on that HW output (aka "submix")
