Accessing files on external storage

[LightTemplar]

Description
Nextcloud supports external storage, such as ftp or samba shares. I would like to work with files on such storage. For now, if I choose a folder from such storage to add as target directory into task, nothing happens. As adding of local directory works, I suppose, Media DC doesn't support external storage yet.

Example
I'm using Nextcloud for important files and TrueNAS as media server (with Jellyfin etc). So, I would like Media DC could check files on TrueNAS.
