Rekordbox CFX problem and fastbutton

Hello, when I enter the record box (all versions), the CFX button lights up by default, in this case "Filter" in the user. If I connect it to XDJ -Xz then I have to turn it off first, every time because if I use something else, it will also turn it on automatically. It would be nice if this CFX button was not active by default, only if I switched it on manually.
Here I would like to ask again so that I can order the CFX seven hotkeys.
Eg: I want the CFX to be: "C" hotkey. If I set up "JET" cfx, when using XDJ XZ I would just press the letter "C" on my laptop and turn it on, I could use it more easily with XDJ XZ. It would be nice to develop this feature. Thanks.
