Possibility to change subversion comments in GUI

Sometimes a part of a subversion comment is wrong or completely missed. In this case we have to change it during review. A very nice feature would be if collaborator offers possibility to change the subversion comments directly in GUI. The subversion command for changing the commit comment is as follows: (hint: in config propedit/propset has to be allowed) $svn propedit -r N --revprop svn:log URL $svn propset -r N --revprop svn:log "new log message" URL
