Replace ‘automotive’ in admin panel

Hi

I added modification redirect category pages as search results pages, and I am wondering if I can instead of doing this:

Replace ‘automotive’ with your category slug on line:

$categorySlug = ‘automotive’;

in the file:
wp-content/plugins/ymm-search/Block/Selector.php

Can you add replace slug (like a text field) in the YMM Search admin panel instead of going to the file and replacing the ‘automotive’ slug with yours category slug?

Thank in advance
