is there a way to update multiple records including upsert on linked records? 

// fld4nItZFaesqE3hi: 'Pet-Dose' is a linked record
 chunk=[ {

    id: 'recDZL0CMwcu8nh0w',

    fields: {

      fld4nItZFaesqE3hi: 'Pet-Dose',

      fld6kqVwPYlYRsI73: 0.715

    }

  },

  {

    id: 'recoAcgIEbo0vXqRv',

    fields: {

      fld4nItZFaesqE3hi: 'Pet-Dose',

      fld6kqVwPYlYRsI73: 1

    }

  }];

 //update records

        chunks.forEach(function (chunk) {

            airtable.base(baseID)('Artikel').update(chunk, {typecast:true}, function (err, records) {

                if (err) {

                    console.error(err);

                    return;

                }

             

            });

        });
