Hot-Plug-Support for external Hardware

I know i´ve did this Request one time before, but this is for my Using of an Audio Sequencer so essentially important. Nowadays I´ve got Ableton Live and even FL Studio, too, which could handle that perfectly. This is really a Reason for me to not using Cubase, i really have to say.

if it won´t come on future proximated Versions or Updates, I´m ashamed to say, that i have to go in friendship with another Software deeper, instead of travelling with Cubase.

Already in Cubase 9.

Why i isn´t in the Descripton for Cubase 9?
