I make saveGame function and I have 6 slots for saving. How can I say, to which slot should I save data? Should I create variables for each of 6 slots

```
 private int currentActiveSlot;
 private int latestSaveSlot;
 const int _numberOfSlots = 7;

 string[] dateTime = new string[_numberOfSlots];
 int[] actNumber = new int[_numberOfSlots];
 int[] stepNumber = new int[_numberOfSlots];
 int[] transformPositionX = new int[_numberOfSlots];
 int[] transformPositionY = new int[_numberOfSlots];
 int[] transformPositionZ = new int[_numberOfSlots];
 int[] transformRotationX = new int[_numberOfSlots];
 int[] transformRotationY = new int[_numberOfSlots];
 int[] transformRotationZ = new int[_numberOfSlots];

 void Start()
 {
     latestSaveSlot = PlayerPrefs.GetInt("latestSaveSlot");
 }

 public void ButtonSave()
 {
     // How to say, to which slot should I save?
     latestSaveSlot = currentActiveSlot;
     PlayerPrefs.SetString("date time", "");
     PlayerPrefs.SetInt("act number", 0);
     PlayerPrefs.SetInt("step number", 0);
     //..      
     PlayerPrefs.Save();
     dateTime[latestSaveSlot] = PlayerPrefs.GetString("date time");
 }

 public void ButtonLoad()
 {
     dateTime[currentActiveSlot]  = PlayerPrefs.GetString("date time");
     actNumber[currentActiveSlot] = PlayerPrefs.GetInt("act number");
     stepNumber[currentActiveSlot] = PlayerPrefs.GetInt("step number");
     //..
 }

```
