How specify additional argument

My sf.net account requires me to first issue a 'create' command to setup remote shell.

I now have to manually run 'ssh -t user,proj@shell.sourceforge.net create' to start the shell and then enjoy the easiness of WinScp. I could not find how to do it in WinScp. Is it supported anyway?

So you need to run the command in a separate SSH session before you can create new SSH/SFTP session in WinSCP?
The shell is create temporarily for a period of time? Or just for a one connection?
