I think you're looking for the -x or -X option. Here's some info (from
prsync --help):
-x ARGS, --extra-args=ARGS
Extra command-line arguments, with processing for
spaces, quotes, and backslashes
-X ARG, --extra-arg=ARG
Extra command-line argument
I hope that helps. I'm glad to hear pssh/prsync are useful to you.
Feel free to ask any additional questions.

Could you describe the use case where appending is desireable? It seems
to me like appending would be error-prone, and it's always possible to
write scripts to combine information after the fact.
