Change API request link to test step -Groovy

Hi 

I am using ReadyAPI and already define Testsuite > TestCase > TestSteps

in some cases , i need to change API Request link of some of test steps to another API , in this case I do it manually, by click on chain icon and open page "Link REST Request" in every test steps

abd it is time consuming activity.

Just wondering if there is any Groovy script to help to me to have bulk update of whole test steps in a test case to save time 🙂
