Is there a way to manually change the Input Key Selector?

Hi, fresh dev here.
I’ve been working on my keybinds menu to enable the rebinding process and ran into a problem. I can rebind the keybinds in the Enhanced Input System just fine, but I couldnt find the option to detect duplicate keybinds there. Now, I understand that its not that hard to make some function that will check for duplicate keybinds and change them back, but here comes my main problem - I cant find the option to change the appearance of the IKS, as its text will keep the name of the pressed (duplicate) button even if I change the binding back.
So, anyone knows how to deal with this problem? Is there a way to change the text on the IKS button that I missed? Maybe there is something I’m doing wrong? How do you deal with detection of duplicate keybinds? Any help is greatly appreciated.
