I would like to know if it's possible to show commit messages from checkins linked to a case in the case history along with existing information like changes to the fields and other comments.

A bit of background:

• I'm using Fogbugz on demand with an external SVN repository.
• I have installed the post-commit script (and TortoiseSVN/Subclipse integration) and that works fine.
• Unfortunately, I cannot install WebSVN or Trac for logs and diffs.
  • (Would installing WebSVN/Trac and linking it to Fogbugz provide the functionality I described?)
