Unfortunately, this behaviour cannot be changed directly. If you prefer not to have category subdirectories created automatically, you can look into the SETTINGS->INCOMING NZBS->AppendCategoryDir option. Otherwise, please create a bug/enhancement request describing your use case, and I’ll see what I can do.
