Works and movements

I notice that on Idagio, the streaming service I use, Works are presented as a total, with subsidiary lines for individual movements. An example is attached. Is it possible to insert these "works" lines into existing files? How would this be done?

It would be interesting to have a look at the extended tags dialogue to have a file as a template.
If this something that happens only within that application, then there is the question: is that data exported to the tags or is only available in the database?

If you need more field names, have a look a the help:
