How to run couple of roles in parallel in Ansible playbook?

I need to run some roles in concurrent mode in Ansible.

I run ansible via:

ansible-playbook install_full.yml --tags "10_clean_up,20_pull_images,30_install_postgres_11,40_install_jboss-eap-7.0" --extra-vars "ansible_user=user ansible_password=password"

The playbook install_full.yml looks like:

- hosts: localhost

  vars_files:
    - "vars/build.yml"

  roles:
    - { role: 10_clean_up, tags: 10_clean_up }
    - { role: 20_pull_images, tags: 20_pull_images }
    - { role: 30_install_postgres_11, tags: 30_install_postgres_11 }
    - { role: 40_install_jboss-eap-7.0, tags: 40_install_jboss-eap-7.0 }

30 and 40 role can be run in the same time (to save some time), is it possible to run couple of roles in parallel, not like now - by order list ?

Thanks on advance!
