Audio channel rooting for TV broadcast

I produce TV segments for a German TV show and export my projects as a PreMaster and Master file. The channel has certain requirements on how the Audio channels have to be rooted and I am still struggling on doing it right with DaVinci Resolve Studio.

Can you help me how to assign the busses to the channels? It would be amazing if you can show a screenshot, on how I have to assign the tracks to the busses.

My project has 8 tracks:
Track 1 Dialogue
Track 2 Dialogue
Track 3 Environment sounds
Track 4 Environment sounds
Track 5 Music
Track 6 Music
Track 7 SFX
Track 8 SFX

Premaster and Master are exported as
MXF OP1a / XDCAM HD 4:2:2 50Mbit + 8CH Audio (24 Bit) 1080i/25

Master:
A1 Stereo PGM Mix L or Mono PGM Mix
A2 Stereo PGM Mix R or Mono PGM Mix
A3 Stereo IT (Music & SFX) L or MonoIT (Music & SFX)
A4 Stereo IT (Music & SFX) R or MonoIT (Music & SFX)

Premaster:
A1 Mono - Dialogue
A2 Mono - Environment Sounds
A3 Stereo - Music
A4 Stereo - Music
A5 Stereo - Music
A6 Stereo - Music
A7 Stereo - SFX
A8 Stereo - SFX

Thank you very much in advance for your help. I am looking forward to hearing from you.

If I remember correctly, DaVinci Resolve does not support stereo tracks in mxf with XDCAM MPEG2...it will split all stereo tracks to 2x mono

Perhaps this post will assist in establishing a workflow outputting deliverables:
