recursive add ??

When adding a new directory in WinCVS why does't it give the user the
option of adding the directory recursively? I'm just trying to add a
new set of directories and files to an existing module that is
organized like this:

ExistingModule
   ExistingDir1
      ExistingSubDir1
      NewDir1
         NewDirSub1
         NewDirSub2

Does anyone have any suggestions for accomplishing this?

Perhaps there is some way to use a variation of import for this?? It
seems that the cvs client included with WinCVS doesn't support doing a
recursive add to add a new tree of files to an existing module.

I could write a python script that would recurse the new directory and
call add individually for each file and directory in the new tree but
this seems like such a basic sort of functionality that I have a hard
time believing that someone hasn't already created good way to do this.

Thanks
