Update Current File From FTP Follow

Is it possible to automatically download a file from the project's associated ftp when you open a file ?
In the same way like it automatically uploads the file on save, but this should automatically download it when you open a file (and maybe inform you about the fact that it changed on the remote server if you try to save it and have it auto-upload).

For an example take a quick peek at dreamweaver's ftp functionality :)

Thank you for your time.
