It is possible to generate cuesheets from the CDTOC tag. What about implementing it in the type:
- for each folder at the same level, do: identify the audio tracks, read their CDTOCs and track number and filenames
(- should there be more CDTOCs present in the same folder, group them and do the following for each CDTOC occurring)
- generate a cuesheet using the track numbers/filenames, and put it in the same folder.
