Overwriting existing directory setup partially copied

Hi,

I have a huge directory/subdirectory setup on a remote Linux machine which takes ages to copy to my local PC, however, the network connection keeps getting annoyingly disconnected from time to time, and to resume a partially copied file structure, the only options available are to overwrite the existing partially downloaded stuff or skip the download altogether. Isnt there an option to compare the file sizes of the already existing files with those at the remote machine and copy a file only if missing in the local PC?

Thanks

It is already on the wishlist.
