Data driven test suite execution

Well, i had gone thro this data driven execution in the soap ui User guide.

I wanted to do know if we can run that in a script .

For example,i have a groovy script which takes the testcases in a test suite and runs them in a loop .
Is there a way to data drive them? meaning each test case should run for sets of data . Just checking ,is there a option like that .

Is the question clear now? pls advice .

Thanks
