Add Specific VST Instrument

Hi, I currently have a button to add VST Instrument Track. Is it possible to add an Instrument track with a specific Instrument?
For example Add A specific Piano patch which is part of Komplete Kontrol/Pianos/Patch 3?
If not, wouldl it be posible to at least have the instrument loaded, Komplete Kontrol, Halion, Viper Etc?

Many thanks

The Cubase plugin can only trigger functions that are available in Cubase. If you can define such a function, e.g., as a key command in Cubase (which I doubt), then the plugin can use it.
