Unfortunately, the Save component cannot save to a save location. However, you can enable FTP upload by using a small script with the external component.
The trick is to build an FTP script on the flyso you can pass a variable with the path to the job file (aka $FFin$).
The following batch file should do the trick:
@echo off
echo user MyUserName> ftpcmd.dat
echo MyPassword>> ftpcmd.dat
echo bin>> ftpcmd.dat
echo put %1>> ftpcmd.dat
echo quit>> ftpcmd.dat
ftp -n -s:ftpcmd.dat SERVERNAME.COM
del ftpcmd.dat
