Out of interest, why use the Synology download station, when you could use NZBGet, SABnzbd on the Diskstation?

I have 3 synology disk stations, so I am interested to see if I am missing something.
I would love to see this added as well. Radarr and Sonarr can both manage torrents and nzb downloads via Download Station so this should be feasible. It's great to have both nzb and torrent downloads managed in one app.
