Terminology note: Below we'll say player for any individual or contestant. Every sport on Playpass has its own terms, so please tell us if we're missing yours.
All schedules on Playpass have the same setup and customization.
You can take any schedule that was made for teams and use it for players (or vice versa). Just rename each team/contestant as a Player and it will just work.
Tap a name to rename it as Player 1, 2 etc or as that player's real name
Playpass Scheduler can handle fixed partner pairs: where 2 players play every game together. For example, rename a contestant to "Kevin & Steph" (or "Durant/Curry") to schedule that pair.
The same goes for 3 or more players, although then you might as well ask for a team name.
The Scheduler cannot handle rotating partner pairs: every game the pair changes partners.
