Upgrade StorageHow to sort by two keys simultaneously?
[Found none discussions of this kind, please refer me to, if a one exists.]
I need to sort by two keys simultaneously.
Namely: if the author is missing, the title should perform the role of the key.
For instance: [consider #14 here]
13. Ekman P. Basic Emotions. Handbook of .....
14. El misterio de la macabra - Barbara Hannigan y la Sinfónica de Londres. URL: https://www........
15. Engel J., Astbury B., Keast H. et al. What is ......
so, #13 & #15 possess an author whilst #14 doesn't.
At the moment I'm having sorting either by an author or by the title, not by both, so, either "El misterio..." goes to the end or to the front.
Any ideas?

CSL has sorting by macro solution,
so in my case it's creating a macro, then a conditional:
>if author exists, sort by author,
>else, sort by the title
