Easy to use import/export from Excel for requirements???

I asked this question last year but am hoping that I might get a better answer this year. We are using PTC and a project management software package for Agile software development. We are really much closer to a Displined Agile Delivery style where we do have some requirements stated upfront and provide more detail as we progress in the project. The software development team really likes their Agile PM software and use it to split requirements and provide more granularity as we move through the project. Our test group really likes to use PTC for locking down the requirements and tracking bugs once requirements and features have become finalized. It would seem to me that we should be able to find a middle ground where we can import and export requirements (user stories) as the software development team does backlog grooming and iteration planning into PTC where our test group can track bugs and also keep the latest version of requirements. Is there any way to transfer back and forth without writing a significant block of XML code and use a very complex import/output tool?

The PM software tool has a very simple Excel import/export tool and is very friendly to this concept? Is the latest version of PTC any better (we are using Version 10)?
