Listing Template for Sub-Categories

Currently, listing templates can only be associated with the main category. Best practices for category trees suggest having a few main categories and many subcategories.

For example, if we have a main category for "Restaurant" and subcategories like "Bar, Café, Snack Bar, Restaurant," etc., it's not possible to assign specific listing templates to each subcategory. Allowing templates for subcategories would enable more tailored listing experiences.
