Use “Check Point” FTP Proxy Authentication Format in WinSCP

Can I use "Check Point" FTP Proxy Authentication format in WinSCP? Basically it's the format like below:

USER %u@%s@%h
PASS %p@%w

This format is supported in FileZilla, don't know if this also works in WinSCP.

Any thought would be greatly appreciated.

Thanks!
