Documentation or Guidance on League Settings

After getting a League created in Zwift Power, I’m struggling to understand the different settings available to configure the league, like the different scoring schemas, or how to create new categories. Could anyone help with these? It would be very helpful to have some kind of manual or guidance on these topics.

I will ask something more concrete
We would like to create specific categories just for people belonging to a specific Zwift Power team. I’ve been playing with the Settings without success so far. Is it actually possible to do? If so, how is it achieved? Thanks in advance
