TSVN equivalent of svn copy -r

I tried to revert a excel file - let's call it table.xls - in a working
directory to a former revision (revision formerRev) and commit it in
order to discard all changes after this revision. When using "Update to
revision" or "Switch" the file in the working directoy really reverted
to revision formerRev but there was no possibility to commit the working
directory because subversion / TSVN recognised no modification. So I
think this is the wrong way.
Using table.xls' log message dialog and right-clicking "Revert to this
revision" results in a conflicted state even though the file was not
modified before. Not what I wanted, too.

The only way I managed to revert the file was

    * SVN deleting table.xls using TSVN
    * using the svn command line client in the working directory: svn
      copy -r formerRev RepositoryURLandPath/table.xls .
    * commiting using TSVN

Is there any way to do the same without the command line client ?

Thanks for your help !

Sven.
