Provide a way to prefix/suffix timestamp for "Rename if file already exists"

[Guru]

It would be very very beneficial if an option is provided, that simply renames the existing file with a timestamp.

e.g. When I upload a file named index.php to a server and if the FileZilla finds index.php already existing on the server it should rename the existing version to index<timestamp>.php and copy the new one from local source. This would be a great versioning feature and will help many programmers.
