Simultanious sFTP Transfer Using a Script

The ability to have WInSCP transfer multiple files simultaneously using a queue similar to the GUI would be helpful. Version 5.7.1 does not appear to support background transfer from a script.

Sample script I am currently using:

option batch abort
option confirm off
open sftp://%sFTP-UID%:%sFTP-Pwd%@%DestServer%
option echo on
cd "%UploadRemoteFolder%"
put "*.bak"
close
exit

We are not planning to support transfer queue in scripting, I'm sorry.
