[GUI] Native toggle for Sprite Swap?

I’ve found similar answers here, but nothing that fits exactly what I’m trying to do here. I have 4 buttons all using a static Sprite Swap for the button texture. When clicked, I’d like the button target to change to the button pressed and stay that way. Leaving all other buttons back to their default image target, except for the button that was clicked. I haven’t done any scripting for this yet, as everything was created within the GUI for unity. Any suggestions on how this can be done?

I have written similar code for my game. When i get back on my computer in a day or so i can post the code that i use here, does that sound good?

Cheers, Oskar
