Full Zoom Out in key editor?

It has probably been asked before, but can’t find it. Is it possible to do a full zoom out in the key editor. Now the zoom out seems to be limited to 10 bars or so,

You can see the minimum and maximum zoom levels according to the position of the zoom slider embedded in the horizontal scroll bar area at the bottom of the Key Editor. It’s not possible to zoom out any further than the minimum value of that zoom slider.

Perhaps something to change in a future version. Having the possibility to zoom out (to the full score) gives a better overview of all CC controllers.
