Is it possible to extract a "subtype"?

Hi,

I'm looking into Arktype for the first time, so please forgive me if this is a noob question

I wanna extract a "subtype"/"subschema" from a schema. I don't know how describe it better other than a code example:

const someScope = scope({
  Endpoint: {
    response: {
      name: 'string',
      age: 'number',
    },
    params: {
      body: {
        name: 'string',
        age: 'number',
      },
    },
  },
}).export()

const Endpoint = someScope.Endpoint

// Should be equivalent to type({ name: 'string', age: 'number' })
const Body = Endpoint.params.body

const someScope = scope({
  Endpoint: {
    response: {
      name: 'string',
      age: 'number',
    },
    params: {
      body: {
        name: 'string',
        age: 'number',
      },
    },
  },
}).export()

const Endpoint = someScope.Endpoint

// Should be equivalent to type({ name: 'string', age: 'number' })
const Body = Endpoint.params.body
