How to call a global script

Hello,

In one of my SoapUI projects, there are a lot of slightly different test cases which all call an identical pre- and postprocessing script. However, each test case contains the script at the moment making it totally redundant. If I adapted one line in one of the scripts, I would have to do that x times.

Is there a way that each test case within let's say a test suite calls one globally written script?

Thanks,
