Is it possible to populate the csv generated song list and make changes to the author then upload back for auto updating songs?
What are you trying to do? That might work, and you could give it a try, but there is a built in author edit interface in OpenLP.
If you right click on any song, and click Edit then go to the `Authors, Topics & Songbooks` tab. There's a button at the bottom labeled `Manage Authors, Topics, Songbooks`. Hit that button and you can globally edit authors.
Yes, I can edit the author and it affects all the songs linked to it but what I am trying to achieve how I can do it for individual songs that has different authors and can easily change it for multiple songs without doing it for each songs.
