Can I call WinSCP script remotely?

Hello,

I have a WinSCP script for file transfer that I need to run between two machines. The issue is that I need to kick off the script from a third machine that isn't the target or the source used for the transfer. Does WinSCP support this?

Thanks in advance.

Sorry, I do not understand.
Where is the script? What kind of script it is? How can WinSCP reach it?
