Respect subfolders when transcoding

[uwuceo]

Multi-CD releases where each CD is in a different subfolder get their subfolders combined, so after transcoding you get one folder with tracks:

Folder

01 aaa
01 bbb
02 aaa
02 bbb
...

Instead of the existing:

Folder

Disc 1

01 aaa
02 aaa
...

Disc 2

01 bbb
02 bbb
...

If there is artwork in a folder, it already gets copied over in the correct subfolder (Disc 1/cover.jpg for example), can the same be done for the tracks?

If that's not possible, maybe there could be a setting to wait after transcoding so you can manually do the subfolders, then press Y to create the torrent and upload it, but this wouldn't be ideal.
