Is there a way to execute one case in command line without creating suite?

i am trying to use one case as script to create test data, not only for tester, so the input test data is dynamic, but i am not sure it is able to trigger one katalon case from my own service. does any one know it or other advices to do my task? Thank you!

Easy work around would be to create a test suite with only one test case in it.

yes that will work, but is there a way to avoid creating many suites?

Unfortunately no, only test suites and test suite collections can be executed from cmd.
