Two Different CVS servers (remote and local) for one project (CVSNT, WinCVS client)

Question

There is a project that uses CVSNT/WinCVS for Version Control. This is the central repository. Locally checked out folders contain hidden sub-folder called "CVS".

I tried to install CVSNT server locally and use second instance of WinCVS to manage(version control) local temporary changes before committing to the central repository.

But that is not working because when checking out from the second(local) repository it still uses "CVS" sub-folder name for its working files.

Anybody knows if it is possible to configure CVSNT server and/or Client to use different name for this sub-folder? And if yes, how?

So far I'm using TortoiseSVN. It creates folders too, but they called ".svn" so there is no interference. It is integrated in Windows shell, which I don't like.
