How do I separate author names with "/" (slash) instead of commas using `natbib` (in LaTeX)?
My question relates to citation (in footnotes) as well as the bibliography. Do I have to configure this in `\setcitestyle` or `\bibpunct`?

An example for comprehension:
as is now:

> 
> Lastname1, Lastname2, and Lastname3 (Year), p. X-Y
> 
> 
> 

as it should be:

> 
> Lastname1 / Lastname2 / Lastname3 (Year), p. X-Y
> 
> 
> 

```
