i.e I just wanna set the tag to ‘Female Vocal; Rave; Psytrance’ (sorting not relevant)
If I use copy/paste, the new tag is overwritten. If I copy and click edit, pasting it will not properly paste the individual values but all of them flattened and joined with '; '.
How can I merge values? (obviously writing a script to preprocess manually every track, copy the old values to another tag, then merge both via scripts and delete the dummy tag is also a NO, since it involves also editing files which don’t need an update/merge)
Definitely a simple contextual menu entry to do this would be much appreciated.
