Describe the feature you'd like to request

In amplify gen2 the eager load allows to fetch nested (one to many) objects. However it does not fetch all the related objects. It would be nice to allow the client to initiate a full load of the related objects. Or if it is possible then it is not mentioned here:
https://docs.amplify.aws/react/build-a-backend/data/data-modeling/relationships/#eagerly-load-a-has-many-relationship

const selectionSet = [
  'id',
  'title',
  'content',
  'tags.*',
] as const;

// this only returns the first 100 tags for each post
const listResult = await client.models.Post.list({
        selectionSet,
      });


// this also does not return all the objects
for (const post of listResult.data) {
        // for each post we load the tags
        const tagsPerPost = await client.models.Post.get(
          {
            id: post.id,
          },
          {
            selectionSet: ['tags.*'] as const,
          }
        );
}

Describe the solution you'd like

const selectionSet = [
  'id',
  'title',
  'content',
  'tags.*',
] as const;

// this way the client would paginate and fetch all the tags until it reaches nextToken null
const listResult = await client.models.Post.list({
        selectionSet,
        fetchMode: {
             tags: "ALL"
        }
      });
// or 
const listResult = await client.models.Post.list({
        selectionSet,
        fetchMode: {
             tags:  {
                limit: 1000
            }
        }
      });

Describe alternatives you've considered

The alternative is to use, but then we loose the typing.

await client.graphql({
        query: /* GraphQL */ `
...
