Menu to choose between different starting planets?

Basically I want to have a menu when someone first logs into the dedi, to have an option to allow players to choose from different planets to start on. Haven't really been able to find any documentation on this.

edit: Looking through the starter playfield yaml I found this:

Code:

   
FixedPlayerStart:
        - Mode: Debug
          Pos: [ -835, 165, -1000 ]
          RotY: 125

        - Mode: Survival
          Spawn: EscapePod
          # Spawn: Structure
          # Structure: "Wreckage"
          # Armor: ArmorLight
          Items: [ "SurvivalTent, Flashlight, AntibioticOintment:2, Bandages:2, StomachPills:2", "SurvivalTent, Flashlight, AntibioticOintment:1, Bandages:1", "SurvivalTent, Flashlight, Bandages:1", "#FreshStart: SurvivalTent, Flashlight, Bandages:1, WaterBottle: 1" ]

So I added this to the 2nd planet's playfield yaml, dropped my universe into the scenarios folder in the single player game. Went to start a new SP survival game using this scenario but I still only get the option to start on the one initial starter planet.

 

update: nvm asked someone and figured it out. Had to classify the planet as a starter by editing the sectors.yaml 'Human:1':

Code:

    Playfields:
      - ['0, 0, 0', Iranor, Iranor, 'Human:1']
