Debugging Test cases

Hello,

I was wandering if there is anyway to debug a test case in soapUI/sopaUI pro.
When I have a normal testcase that just holds couple of test requests, it is easy. I just run every request at a time.
But when I have a test case with a test step to run another test case, I can only run the whole inner test case.
I was wandering if there is anyway to perform what is usually called in debuggers 'step in' into the inner test case, or if anyone has a better idea how to debug it, it will be great.

Thanks in advance,
Barnash
