Single item vs collection

[phsd0]

Let's say I have endpoint /todos with support of all filters that on demand mode provides this endpoint returns only preview of todo items not their full content. And also /todos/:id which returns exact todo item with all data.

In tanstack query i would use ['todos'] and ['todos', someId] keys accordingly. Lets say todo item have a lot of data attached which isn't required to show list of todo but required to present single todo item on separate page.

How to deal with it using tanstack db? I figured out how to deal with list of items from docs:

const todosCollection = createCollection(
  queryCollectionOptions({
    queryKey: ["todos"],
    queryFn: async () => {
      const response = await fetch("/api/todos")
      return response.json()
    },
    queryClient,
    getKey: (item) => item.id,
  })
)

But how I should define collection for single (expanded, full) todo item? What queryKey should I use? How to query this data?
Maybe I missing something but I didn't find anything in docs about this case
