I was able to import channel settings only - but not without issues.
Nuendo created a whole new set of tracks instead of pasting into the tracks I had selected.
It also deleted the audio from the tracks it was supposed to have imported to.

As I indicate in the post, other than that it worked great. I was impressed - in a limited sort of way.
