Unable to Assign Pages Under a Custom Link in WP Nested Pages

Hi everyone,

I’m currently trying to create a hierarchical structure in WordPress using the WP Nested Pages plugin. My goal is to have a custom link act as a “virtual” parent directory without creating a physical page for it. For example:

domain.com/berlin/mein-inhalt

Here’s what I’ve tried:

1. I added a custom link (e.g., /berlin) in the WP Nested Pages interface.
2. I attempted to assign existing pages (like “mein-inhalt”) under this custom link in the hierarchy.

However, it seems the plugin doesn’t allow pages to be nested under a custom link. Every time I try, the custom link stays at the same level, and the pages remain unassigned as children.

Is this functionality supported? If not, is there a workaround to achieve this structure without creating an actual “Berlin” page?

Any help or guidance would be greatly appreciated!

Thanks!
