Keyboard Mapping

Not sure if this is the right place to make a request for a feature but I really hope someone can implement keyboard mapping cause I only use keyboard for all games. I know it might not be a huge crowd asking for it but I would really appreciate it if anyone could do so because its a struggle to play with the default keybinds. There are certain games like wwe and ufc which only run on xenia for my computer which is why I can't use other emulators. It would really be appreciated if possible, thank you.
