Update search params partially by default

[JKupski]

I don't like the way I have to update my search parameters when having a search state with more than one property.
navigate({ search: (prev) => ({ ...prev, tab: tvalue, }) })

Is there an idea for a better solution or is it an option to modify the update behaviour of the navigate state, so that by default only the state passed is updated? When I want to set my state to null or undefined, I want to do that explicitly.

What are your thoughts about this behaviour? Better solutions are welcome :)
