Can you change your customisable error messages in WinSCP

Can you do it? :(

Also can you add subdomains to your domain from there?? :?:

Thanks

I do not understand neither request of yours. Please try to explain.

FOr instance change your server so that instead of the windows 404 error, you can have your own!

What server? Do you mean HTTP 404 error message? I do not understand what it has to do with WinSCP.
