What you need to do is a property transfer. There's several ways to do this, but the easiest i find considering you're gonna reuse the responseId is to save the responseId to a property step. Once the responseId is saved to a property step you can reuse later in your test.
Some basic steps
On the Rest request's response, highlight the responseId attribute and click on the 'Transfer to'
Select 'Add Properties Step'
Click 'Ok' on 'Create Properties Step' dialogue
Click 'Ok' on 'Create target property' dialogue
Click 'Ok' on the 'Transfer to Property' form
The above generates a 'PropertyTransfer' step and a 'Properties' step.
The resultant of the above steps is that you can then reuse the responseId property value saved in the Properties step on subsequent steps in your test case.
Hope this was clear!
