Can I alter the list of categories displayed in the dropdown?

Hi everyone! Here’s the use case.

We showcase the Wishlist category with lots of subcategories on our homepage, so the general list of categories is huge and inconvenient to navigate. Is there maybe an option to display only Wishlist category with its subcategories in the dropdown to simplify things?

Thank you in advance!
