the order of the long-pressed secondary characters

I use the SwiftKey keyboard on Huawei mate 10 pro. In Hungarian, therefore, because of the difficulty of our language, we use a lot of accented characters, but in the case of the pop-ups of the ignored character without the accent, the accentuated equivalent of the character does not jump, so it is lengthy to enter the accented characters. I really like SwiftKey and I'm already accustomed to it, so I just do not want to replace it because I can not customize some things at the moment, is it possible to develop it and complement it with such an option?
