Can you refer in groovy to the last executed teststep?

I have a testcase with 2 teststeps.

First teststep is a SOAP requests that gives an XML response.

Second teststep is groovy script that will save the XML response.

Groovy script: 

def date = new Date()
def dts = date.format("yyyy-MM-dd-HH-mm-ss")
//Write Request to XML File
def myXmlRequest = "C:/Data/Request"+dts+".xml"
def request = context.expand('${SOAP Request}')
def req = new File(myXmlRequest)

req.write(request, "UTF-8") 

Is there anyway that you can say in groovy just save the result for the last executed teststep instead of now using context.expand('${SOAP Request}')
