How to Change Menu Button Rollover States with GameObjects

Hello!

My goal is to have 4 different GameObjects that are SetActive(true); or SetActive(false); based on when the button is pressed or when it is rolled over with the mouse. They are all UI Images.

I currently have this working for 3 States (Normal, Normal-Rollover and Selected) in my script that I have pasted below but I can't figure out how to add the extra 4th State being "Selected-Rollover".

What I want to add to the code:
if Normal = true then the rollover image should be Normal-Rollover
else if
Selected = true then the rollover image should be Selected-Rollover

This is my Button Controller script:

 public class ButtonController : MonoBehaviour
 {
 
     public GameObject normal;
     public GameObject selected;
 
     public GameObject normalRollover;
     public GameObject selectedRollover;

     public void ActiveButton()
     {
         // Sets the button to Selected when you click on it
         selected.SetActive(true);
         normal.SetActive(false);
     }
 
     public void DeActiveButton()
     {
         // Sets the button back to Normal when you click on another Button
         normal.SetActive(true);
         selected.SetActive(false);
     
     }
 
     public void OnPointerEnter()
     {
         normalRollover.SetActive(true);
         normal.SetActive(false);
     }
 
     public void OnPointerExit()
     {
         normal.SetActive(true);
         normalRollover.SetActive(false);
     }
 
   

This is my GameManager script

     public Button[] panelHatButtons;

     // NORMAL ROLLOVER 

     public void PanelHatPointerEnter(int buttonNum)
     { // Gets sent the int index of the button from the OnPointerEnter Event Trigger
         for (int i = 0; i < panelHatButtons.Length; i++)
         { // Loop through the array buttons
             if (i == buttonNum)
             { 
                 panelHatButtons[i].GetComponent<ButtonController>().OnPointerEnter(); 
             }
 
         }
     }
 
     public void PanelHatPointerExit(int buttonNum)
     { // Gets sent the int index of the button from the OnPointerExit Event Trigger
         for (int i = 0; i < panelHatButtons.Length; i++)
         { // Loop through the array buttons
             if (i == buttonNum)
             { 
                 panelHatButtons[i].GetComponent<ButtonController>().OnPointerExit();
             }
 
         }
     }

     // BUTTON SELECTED 

     public void PanelHatButtonPressed(int buttonNum)
     { // Gets sent the int index of the button from the OnClick()
         for (int i = 0; i < panelHatButtons.Length; i++)
         { // Loop through the array buttons
             if (i == buttonNum)
             { /
                 panelHatButtons[i].GetComponent<ButtonController>().ActiveButton(); 
             }
             else
             { // This is every other button
                 panelHatButtons[i].GetComponent<ButtonController>().DeActiveButton();
             }
         }
     }

Any advice/tips you could offer would be super appreciated! :-) Thank you so much!

@evskii Hello! I hope you don't mind me tagging you, I thought I would since I'm using the script you helped me with a few days ago and I have just attempted to add Rollover states to it. I got stuck on this part. Thank you!
