Freeze function for MIDI tracks

Why can VST Live not have that?

I think it woulnd’t be too hard if implementing this function. Doesn’t it exist in Cubase as well?

To me it seems way too complicated and inconvenient of having to do this externally in a DAW. One click on the track - freeze - one more click - unfreeze. That would make things quite perfect for me, as I could do in Ableton Live…
