How do I automatically insert a REST test step into a SoapUI test using Groovy?

My team and I currently have a few hundred tests scripted which we want to start automating. Instead of manually creating test cases in SoapUI, I have written a script which generates test cases with default properties. My next task is to insert a sample request for every REST service we have defined in our SoapUI project; I'm not too sure where to start with the SoapUI Groovy API, but below is a sample of my test creation script so far:

import com.eviware.soapui.impl.wsdl.teststeps.registry.GroovyScriptStepFactory
import com.eviware.soapui.impl.rest.RestResource;
import com.eviware.soapui.impl.wsdl.teststeps.registry.RestRequestStepFactory
import com.eviware.soapui.config.TestStepConfig
import com.eviware.soapui.impl.rest.RestRequest;
import com.eviware.soapui.impl.rest.RestService;

listOfTestCases = [
'Address Lookup with valid PostCode',
'Address Lookup with Valid CompanyName',
'Address Lookup with Valid Street',
'Address Lookup with Valid town',
'Address Lookup with Valid CompanyName & Postcode',
'Address Lookup with Valid Street & Postcode',
'Address Lookup with Valid Town & PostCode',
'Address Lookup with Valid CompanyName & Street',
'Address Lookup with Valid CompanyName & Town', 
'Address Lookup with Valid Street & Town',  
'Address Lookup with Valid Postcode, CompanyName, Street & Town']
for (String testCase : listOfTestCases) {
   tc = context.testCase.testSuite.addNewTestCase(testCase)
   tc.addProperty("testcycl-id") 
   tc.addProperty("cycle-id") 
   tc.addProperty("test-id") 
   tc.addProperty("run-id") 
   tc.addProperty("test-config-id")
   tc.addProperty("test-step-id")
} 

My question is thus: For every test case I have created, how do I insert one of every REST request?
