Control Zoom on map with Di2 buttons

I know it has been discussed a lot in the past, but I cannot believe Garmin still did not make this possible:

Why GARMIN is not implementing the ability to zoom in and out with the Di2 buttons? Wahoo has this since ever, and it is hard to believe that it's technically impossible for Garmin to do so...

Anyone else missing this or is there any workaround?
