Advanced Wave Spawner.

Hi, how can I make different enemies spawn at certain spawnpoints, and not at random spawnpoints, as now in my script. Can I do it in wave spawner? For example rotating platforms spawn at (0,0,) and enemies at (10,10) and etc. Here's my current script if you need one:

 `public class WaveSpawner : MonoBehaviour
 `{
     public enum SpawnState {SPAWNING, WAITING, COUNTING};
     [System.Serializable]
     public class Wave
     {
         public string name;
         public Transform enemy;
         public int count;
         public float rate;
     }
     public Wave[] waves;
     private int nextWave = 0;
 
     public float timeBetweenWaves = 5f;
     private float waveCountdown;
     private SpawnState state = SpawnState.COUNTING;
     private float searchCountdown = 1f;  
     public Transform[] spawnPoints;
     void Start()
     {
         waveCountdown = timeBetweenWaves;
     }
     void Update()
     {
         if(state == SpawnState.WAITING)
         {
             if(!EnemyIsAlive())
             {
                WaveCompleted();
             }
             else
             {
                 return;
             }
         }
         if(waveCountdown <= 0)
         {
             if (state != SpawnState.SPAWNING)
             {
                 StartCoroutine(SpawnWave(waves[nextWave]));
             }
         }
          else
             {
                 waveCountdown -= Time.deltaTime;
             }
     }
     void WaveCompleted()
     {
          Debug.Log("Wave Completed");
          state = SpawnState.COUNTING;
          waveCountdown = timeBetweenWaves;
          if(nextWave + 1 > waves.Length -1)
          {
              nextWave = 0;
          Debug.Log("Completed all waves! Looping");
      } else {
          nextWave++;
      }
      
 }
 bool EnemyIsAlive()
 {
     searchCountdown -= Time.deltaTime;
     if(searchCountdown <= 0f)
     {
         searchCountdown = 1f;
         if(GameObject.FindGameObjectsWithTag("Enemy") == null)
     {
         return false;
     }
     }
     return true;
 }
 IEnumerator SpawnWave (Wave _wave) //want to wate a certain amount of seconds in metod
 {
     state = SpawnState.SPAWNING;

     for(int i=0;i< _wave.count; i++)
     {
         SpawnEnemy(_wave.enemy);
         yield return new WaitForSeconds(1f/_wave.rate);
     }

     state = SpawnState.WAITING;
     yield break;
 } 
 void SpawnEnemy (Transform _enemy)
 {
     //SpawnEnemy
     Debug.Log("Spawning Enemy" +_enemy.name);
     Transform _sp = spawnPoints[ Random.Range (0, spawnPoints.Length)];
     Instantiate (_enemy, _sp.position, _sp.rotation);
