You can configure external connections that can be referenced a later use.

Create a User Connection Group specifically named "ConnectionProfiles" , on Preferences->IP/servers page.\\
Go to user Manager, select the "ConnectionProfiles" group, create a new user, add to it a remote VFS named specifically "server" \\
Configure this VFS item to point to a remote location ( in this example I have 2 accounts with an SFTP and an HTTP profile)\\
Then use in Job tasks the syntax {connect_start}profilename{connect_end}.\\

The example job here finds files in a local folder, loops through both connection profiles, then pushes the files onto both locations.\\
