Postman doesn't do that but you can run multiple curl
requests asynchronously in Bash:
curl url1 & curl url2 & curl url3 & ...
Remember to add an &
after each request which means that request should run as an async job.
Postman however can generate curl snippet for your request: https://learning.getpostman.com/docs/postman/sending_api_requests/generate_code_snippets/
