BD Copy Allow us to add same source multiple times

[tyrindor]

Please allow us to add the same source (mainly .iso) as many times as we need in the BD Copy tab. Currently if you drag the same *.iso in twice, it only adds it once. Making it impossible to do a queue/bulk processing in BD Copy mode from the same source.

Examples:
3D, Extended, Uncut, Director's Cuts Movies. Currently the only way to rip 2 different playlists from an ISO, and keep them in ISO format, is to do them one at a time in BD Copy.

Thanks.
