First, I would like to give credit to the person who commented the configuration I am using from reddit: u/SpartanHeavy

This is the configuration for "Send to Device" from Calibre:

{series:||/}{series_index:|| - }{title}-{authors}

This is the original picture he commented:

Explanation:
This configuration creates a Series folder if a book has existing series metadata. The problem is that all other books are then sent to the root folder without organization.

Is it possible to create an if-else condition for configuring Calibre? I want it so that if a series does not exist, an "Author" folder will be created instead. I tried to create an if-else condition with this code but it didnt work:

{#series:|{series}/|}{authors}/{title} - {authors}

All series got pasted into their author folders.

As a last resort, I know that I can make Series a subfolder of Author

EDIT:
as per @chaley, this is the code that works:

{series:'ifempty($, $authors)'}/{series_index:|| - }{title} - {authors}
