No, because you're specifically stating that path in the Destination string, and you (obviously) have the option set to create it if it doesn't exist. Problem is, you can't turn that option off without defeating the logic that creates such folders for you (that don't yet exist) to put files in the next time there are some files to copy. Catch-22...the creating of the folders (if necessary) is done before the scan (otherwise there's nowhere to scan...), hence it can't decide whether to create it based on 'scan=no files', because it doesn't yet know that's the case. There's no code in Pro to check that afterwards.
The only thing I can think of is to use a script or batch file in Programs-After (and pass it the value of %_Destination% as a parameter) and get the script (etc) to check if that relative path is empty, and if so, delete it again.
