Question about set replay oberver perspective

API provides a sc2::ReplayPlayerInfo to get the player's information in every replay. For example, the first player ID is 0 and the race is Zerg, the second player ID is 1 and race is Protoss. I want to analyze the replay just using the Zerg's perspective, but I didn't find the function in Coordinator or ReplayObserver to set the perspective before starting replay game. Will player 0's perspective be used by default when loading the replay?
