@Bilkoff: I recommend to use Crawljob/Folderwatch for this, see
https://support.jdownloader.org/Know...ch-basic-usage
you can create Crawljob files and either add/place into folderwatch and there you can specify eg custom download folder/name and other properties.
You can also use Packagizer Rules and create rules that match on certain conditions eg name in URL or sourceURL...see
https://support.jdownloader.org/Know...paketverwalter
and then change download folder/name and other properties.
