Show threads as trees in Outlook for the web

Say I had an exchange of mails with my mom and dad, what I see in Outlook for the web is something like:

  papi  mami  papi  son  mami  son  papi

but I'd prefer something different, that is a tree

papi  mami    papi  son    mami      son      papi

I don't think this is possible, but who knows?

Is it possible, using Outlook for the web, to show an email thread as a tree?
