Hmmm, do you mean someone posts something like: "I take a train from your city, London, to Munich, see whatever is on the way as well as what is in Munich."

Then, another person posts: "I take a bus from Munich to Rome, seeing whatever is on the way as well as what is in Rome."

These posts would be with a description of what is on the way, rather than what I wrote there, but, is this what you are wanting to do?
