Combinging Parallel RSpec results


I’ve managed to get our CircleCI suite running with RSpec in parallel builds.
But now I’m wondering, how do I combine all the results afterwards to get a single output?
Right now I do the following:

      - run:
          name: "RSpec Test Suite"
          command: |
            ./cc-test-reporter before-build
            bundle exec rspec \
            --profile 10 \
            --color \
            --require rspec_junit_formatter \
            --format RspecJunitFormatter \
            --out ./tmp/test-results/rspec/results.xml \
            --format progress \
            $(circleci tests glob "spec/**/*_spec.rb" | circleci tests split --split-by=timings)
      - run:
          name: "Code Climate Test Coverage"
          command: |
            ./cc-test-reporter format-coverage -t simplecov -o "coverage/codeclimate.$CIRCLE_NODE_INDEX.json"
      - persist_to_workspace:
          root: coverage
            - codeclimate.*.json
      - store_artifacts:
          path: ./tmp/test-results
      - store_test_results:
          path: ./tmp/test-results

But this only reports from the first container in the overview. What I want is to have the entire output when the tests are finished, not just form a single container. Is this possible?
Couldn’t find it in the documentation.
