Multiplayer Question - Character selection Before/After Server Travel

Hi,
If I don’t choose a character bp to spawn in my game mode does the engine auto spawn one like the default ThirdPersonCharacter? (I’m using the ThirdPersonCharacter Template)
Right now I have to destroy the one that spawns automatically, then I spawn the character blueprint I want then I possess it and it works fine, but can’t I just have it load the right character bp in before/after server travel?
