Would be nice to be able archive messages

Hello. It would be nice to have a feature so that you can archive messages, I have 3 messages from the same person in Hosting as some dates got changed, I dont know if the user should just have changed the date on the original request, I have not used the app as a couchsurfer before only host, but as mentioned would be nice if there was a way to archive the 3 messages threads so I would only see the active one, if this is already possible, please tell me how so I can do it.
Bwt Awesome site.

Greetings Thomas.
