No. You just set/override properties on the device that the machine created.
I thought we already had this, but it looks like the closest we have is
-global.
Something like "-property /devicepath/propertyname=value".
This is something we need anyway. Creating new devices with -device is of
very limited value if you can't link existing device properties to that new
device. Remember that in the new world order we don't have magic bus-device,
everything is done via link properlties.
