programm change (GM)possible?

As I want to use Dorico for teaching and in some places I want a config as light as possible. So I don’t want to use Hallion as vsti.
I installed the Roland Canvas (very light) using the white list: it’s ok but when I play have a piano sound in all the instruments so I must reassign the sound.
If I import a midifile, the instrument’s sound are all “piano”
So can you tell me how Dorico handle the progamm change?
Name doesn’t send programm change ?
General Midi?

It’s allways great to have a vsti as general mid vsti very standard like Roland canvas
Best regards

This isn’t possible at the moment, but it should be once we have support for expression maps which is something that will come in an update soon.

thanks great!
