My situation is W11 with 2 audio interfaces connected and Cubase 13 Pro.
On some projects I use my Focusrite and on others my Audient.
When I switch from project to project, I have each time to reconfigure Cubase Studio.
It could be very helpful to have the current audio interface parameter attached to project rather than to Cubase instance.
I hope I am not claiming for some existing feature ? I would be happy to discover it.
