I have some m4a audio book files that I would like to add a "series" and "series-part" to.
When I go to "customise columns" and add the series and series-part they do appear as columns, but I am unable to edit the field on any m4a files.
However if I go in to extended tags I am able to create the series and series-part tags and populate them with data. But I am still unable to view these fields on the main panel.
Is it possible to display these and edit them on the main panel?
