The best solution will depend on the number of files in the special
groups.

Since you say the number is small, I suspect that something simple like:

  rsync -hia /path/to/sync/common remotehost:
  rsync -hia --ignore-times /path/to/sync/groupN remotehost:

will be close to optimal.

Another option is to build an --exclude-from list for the files in the
special group and apply it to the first rsync.  Then you can run the
second rsync without the --ignore-times, which may result in faster
overall throughput.

FWIW, I think you will find the -hi output more useful than the -v output.
