Hopefully I saved this correctly?
In this scene: bus 1 comes out aux 1, bus 2 comes out aux 2, bus 3 comes out headphone left, bus 4 comes out headphone right, the mono highpassed signal for your tops comes out main left, and the lowpassed signal for your subs comes out main right. I'll use a TRS to dual TS splitter cable (AKA "insert" cable) to get the headphone out into two channels on my NU4-6000 monitor amp.
I have the bass set up for channel 11 which has a tube stage inserted and it then goes through the pitch shifter then to the main right - I use two bass cabs for subs so want the full range bass signal in those instead of split between the tops and subs like everything else. Feel free to change that if using normal subs.
Please comment if you find anything wrong or if you can improve over what I did .
