Data Gen configuration for multiple responces

I have a test step in one test case and I want the response values to another test case test step.

in 1st test step I have response of 20 values. if I want to use the 20 values to another test step of another test case.

in this condition I am using the data Gen, I added a property and gave the xpath link, it copied the value what I want. I can use it in another test step request.

But if I want the 20 values not the one value, how can I do this

In the configuration window, I need to update the xpath of single value or what I need to do.

Can any one help me.
