How to spawn a different actor/characters?

So I’m working on a multiplayer Gamemode blueprint and I want to be able to find a way to spawn a different character(s). Like for an example, currently the blueprint is spawning the default “ThirdPersonCharacter” because I chose it to do so. But lets say if I were to import another character that I would want to use, how will it be possible for me to spawn that new character without having to always go back and change the spawn actor blueprint all the time in order for the blueprint to have the ability to spawn any characters from my roster? I need to find a solution since the project I’m working on will have different characters that I’ve been working on for the past years. Thanks for your time.

Note- This is a class blueprint and I’m using a spawn players function.
