Online multiplayer P2P - How to choose Player Character Instance

I use P2P to make my online multiplayer game. Each player will store their own client ID unique numbers. For now, every time i want to make change to ONLY my player’s character object, in the event i need to repeat for every instance and check whether the instance object’s client ID variable (object variable) is the same as my client ID (global variable). Is there any other way? Maybe like an event where we can store a pointer towards certain instance of object (my player character)

Thanks!

Saw this video a while ago where there is multiple players, there is also download link for the project in the description, hope it helps! https://www.youtube.com/watch?v=4tCsBGDxvHA
