Can I loop script base on user input alert answer?

Hi, I would like to ask if its possilbe to loop script base on user input alert answer?

What I would like to get is something like:

def answers = ["YES","NO"]
LOOP:
def mapSuite = []
def mapCase = []
testRunner.testCase.testSuite.project.getTestSuiteList().each(){
   mapSuite.add(it.getName())
}
nextSuite = [UISupport.prompt("Next Suite", "Select Suite", mapSuite)]
testRunner.testCase.testSuites[nextSuite.join()].getTestCaseList().each(){
   mapCase.add(it.getName())
}
nextCase = [UISupport.prompt("Next Case", "Select Case", mapCase)]
def tc = testRunner.testCase.testSuite.project.testSuites[nextSuite.join()].testCase[nextCase.join()]
def runner = tc.run( null, false )
log.info nextSuite.join() + " - " + nextCase.join() + " Status: $runner.status"
answer = [UISupport.prompt("Continue?","", answers)]
if(answer.join() == "YES"){
< go back to LOOP >
} else{
log.info "DONE"
}

Right now I have something similar in every TestCase TearDown Script, where I can either tell it to stop or go to next Case. Problem with this is that I have multiple Cases runing at the same time waiting to finish TearDown Script, all of them ending at the same time when I tell it to stop. (run Case1 > run Case2 > run Case 3 > end Case3 > end Case2 > end Case1)

I am just curious if its possible to have only 1 Groovy script that would handly all of it so cases end before I start next one. (run Case1 >end Case1 > run Case2 > end Case2 > run Case3 > end Case3)

 

Thanks for answers
