Ok, I got to touch on this again as it would make life much easier not having to manually update my m-TAGs to add the data for hidden tracks.
Otherwise I'd never be sure if there's a chance to get the component doing this. (or if it is even already possible ~wishful thinking~ )
Given the following release: https://www.discogs.com/Amy-Winehouse-Frank/release/7340147 (format is not uncommon)
and a playlist view produced with m-TAG pointing to a cue sheet (to split off the the hidden tracks, see screenshot).
and Discogs json data containing the track listing as in below code block (note: "extraartists" data removed to reduce size)
"tracklist": [
{"duration": "0:21", "position": "1a", "type_": "track", "extraartists": [...], "title": "Intro"},
{"duration": "3:34", "position": "1b", "type_": "track", "extraartists": [...], "title": "Stronger Than Me"},
{"duration": "5:17", "position": "2a", "type_": "track", "extraartists": [...], "title": "You Sent Me Flying"},
{"duration": "1:34", "position": "2b", "type_": "track", "extraartists": [...], "title": "Cherry"},
{"duration": "3:03", "position": "3", "type_": "track", "extraartists": [...], "title": "Know You Now"},
{"duration": "3:21", "position": "4", "type_": "track", "extraartists": [...], "title": "Fuck Me Pumps"},
{"duration": "2:10", "position": "5", "type_": "track", "extraartists": [...], "title": "I Heard Love Is Blind"},
{"duration": "2:49", "position": "6a", "type_": "track", "extraartists": [...], "title": "Moody's Mood For Love"},
{"duration": "0:40", "position": "6b", "type_": "track", "extraartists": [...], "title": "Teo Licks"},
{"duration": "2:09", "position": "7", "type_": "track", "extraartists": [...], "title": "(There Is) No Greater Love"},
{"duration": "5:17", "position": "8", "type_": "track", "extraartists": [...], "title": "In My Bed"},
{"duration": "3:20", "position": "9", "type_": "track", "extraartists": [...], "title": "Take The Box"},
{"duration": "3:25", "position": "10", "type_": "track", "extraartists": [...], "title": "October Song"},
{"duration": "3:30", "position": "11", "type_": "track", "extraartists": [...], "title": "What Is It About Men?"},
{"duration": "5:01", "position": "12", "type_": "track", "extraartists": [...], "title": "Help Yourself"},
{"duration": "4:15", "position": "13a", "type_": "track", "extraartists": [...], "title": "Amy Amy Amy"},
{"duration": "0:51", "position": "13b", "type_": "track", "extraartists": [...], "title": "Outro"},
{"duration": "4:13", "position": "13c", "type_": "track", "title": "Brother"},
{"duration": "3:57", "position": "13d", "type_": "track", "title": "Mr. Magic (Through The Smoke)"}

How much chance is there to get the discogs data mapped 1:1 to the playlist track listing (so as not to lose track credits and information stored in "extraartists" for the tracks considered 'hidden") ?
Since I'm using m-TAGS the tag data never reaches the actual media files. But even if someone has physically spliced the hidden tracks off to separate tracks, a 1:1 mapping would be very helpful when possible.
