Network Start Position component in Photon Unity Network

I need some way to spawn players in one room in different position using Photon Unity Network, just like the component Network Start Position in the normal unity networking,

You can always script some algorithm for a simple Instanciation, for example:

Vector3 startPos;
            startPos += startPos.forward * 2;
            Instanciate (prefab, new Vector3 (startPos.x, startPos.y, startPos.z), Quaternion.identity);
