My suggestion is the following.
It would be nice that you could store your instrument track with its settings (including sends, expression maps, etc.) as a file in a folder of your choice. Then, you could open the media explorer (or any explorer outside Cubase) and drag and drop that track to your project.
In 10.5.2 you can do this with Audio.
Of course, the other way around such be implemented: To convert a track to track file just drag and dropping it from Cubase to the media explorer.
I know there are presets, but they don’t work well. First you have to find them, which is not as easy as it seems (they are a bit hidden) and then, every time you select a preset (just click on it) it loads to memory, slowing your speed. It’s not very convenient.
The solution of having everything in the media as common files is better in my opinion. Much simpler than the different presets. They are basically the same, but the track files would be faster to find.
This will be useful to work with orchestral stuff. Instead of having a 1000 disabled and hidden track template, you have your files in the Media explorer. Then, you choose what ones you need for your project from the media. If you are trying different ones, you can have both and then hide and disable the ones you’re not going to use. Or you can disable a file if you used it to render-in place something.
I think Studio One 5 works like that. Reaper also does something very similar.
