In the meantime, I have a decent-ish solution for X56 users.
I set the pinky scroll wheel on the throttle to RADAR UP/DOWN (= and - keys by default in-game) ONLY on release with a 0.05s delay in the profiler.
Setting it "on-press" is an issue since the buttons themselves tend to get stuck in between scrolls. At least for me.
I added a 0.05s delay since DCS seemed to have a problem registering input with a 0s delay.
This requires a good amount of scrolling sometimes but it frees up some buttons.
If someone knows of any better alternative solution, please share.
