Remote datasource function instead of fetch url

It seems the current way where you have to define a fetch url as string is very limited.
What if I want my url ro change as per other select, what if my fetch requires more search params which depends on other selections by the user.

Isn't it better to offer a function call which returns new items a better approach?

Sorry it seems I missed the fetchCallback option
