Can't use controller in Export Mode, unbelievable!

Hi,

I've been using a XDJ-XZ to mix and Export Mode on my computer for track preparation.

Decided to buy a DDJ-FLX4 this week just so that I could use it to prepare tracks in Export Mode in front of the computer, using a small portable controller without having to use the keyboard so much.
Just found out that AlphaTeta decided we can't use a controller in Export Mode, too bad I didn't do my research first, as many posts do say that; didn't care to check because I don't see any sane reason for not being able to.
What gives? Some of those posts are old, has there been any update on using a controller in Export Mode?

In this topic https://community.pioneerdj.com/hc/en-us/community/posts/22976943958169-Use-DJ-Console-to-control-Export-mode an user says he was able but doesn't remember how?
"What is strange that yesterday I've managed to Start/Pause, CUE and have channel level LEDs on a DDJ-RB in Export mode - don't ask me how because I really don't know to reproduce."

Please don't tell me to use Performance Mode because it can do everything Export Mode can do. Export Mode is a lot more friendly and easy to use to prepare tracks!

Is there any workaround? Seems like I wasted my money buying a DDJ-FLX4 just to prepare tracks, sad.

Thanks and best regards,
John
