if you could be able to click a button to use another repel other than having to click the button on the screen i feel like it would be a great quality of life change. its not too big of a deal but sometimes if you are watching a movie or video and hunting on the side you have to switch your attention every time just to click the yes 

Heyho, I am not sure if you are aware of it but it's not only intentional that it's not possible to bind it but the window even has a random factor where it appears to make it harder for macro users to automate it. Right now, I am not a fan of it but I am not totally against in the future since I plan to add full controller support.
