I've got tracknumbers in the wrong field (Comment) on a large number of FLAC filesets, and would love it if some kind person would tell me how to fix this easiest please.
On some filesets
(1) the tracknumbers look like T01...T12, on others
(2) the tracknumbers look like d1t01...d1t12...d2t01...d2t14
In case #1 I'd like to MOVE* the last two characters of Comment to Track and set Discnumber to "1".
In case #2 I'd like to MOVE the last two characters of Comment to Track and MOVE the second character of Comment to Discnumber.
*By move I mean after the operation I'd like the Comment field left empty.
