It kind of works but not clear how I did it.

I wanted to have virtual sets I made in another preset in the current one I am working with.

I managed to open and append the preset with the virtual sets inputs onto my current preset but my file name became the file name of this other preset and I got all the inputs that were also in the virtual sets preset.

Would be nice if in a virtual sets' config screen a button to export "virtual set input"

To then in a new preset add input -> custom virtual set from file and it input all the content/inputs that make up a virtual set from my other preset.
