Other Web Host Settings...in Webproperties/Publish

In XWD Premium 18, can you create subfolders for your main site on your server using this dialogue box? Using the Sub-Folder optional input?

Or does an FTP Client have to be used to create the subfolders before publishing with Xara?

If I am publishing articles into a subfolder example... 'mymainsite/Articles/goose-attacks-mayor/' can I create the subfolders 'Articles" and "/goose attacks mayor/" from XWD 18P before or at publishing the separate articles?

Or there is no way around using Filezilla?

I see other info about earlier XWD versions as a no, but 18 Premium?

Thanks..
