A-B-C setup for Cargo?

I’m just wondering if I want to use an A-B-C and C-B-A route for cargo from my hub.

  1. Can I pickup and dropoff cargo at B going each direction using VIA setup or do I need to setup two schedules for each direction with an hour long layover for the cargo transfer?

  2. Will cargo continue on from B to C even if it says "transfer impossible" (is that for PAX only)?

Thanks in advance.

transfer impossible is both for pax and cargo but this doesn’t affect anything that stays on the same a/c
