How to change the default spawn class for the second player?

Hi guys, I need your help.

I’m trying to make a simple LAN multiplayer demo with the Template FPS. I’ve duplicated the FirstPersonCharacter Blueprint to get 2 Blueprint class. One is named Hunter (default class), the other Monster.
But, unfortunately, I don’t know how to spawn the Monster Blueprint. I would like the first player be a Hunter, and the second a Monster.

Indeed, when I choose 2 players in “Multiplayers Options”, and when I click on Play, my second player is also a Hunter.

I’ve tried with Possess node, but it’s not what I want. How to change the default spawn class for the second player ?

I hope you could help me.

Thanks.
