[composite project] Test Cases rename

Hello,

I want to develop my REST project in SoapUI NG PRO as composite project and put it into git repository. But I have some doubt about file names in saved project. Let's follow that steps:

1. Create new Test Case named 'test1'.

2. Save project.

3. Rename 'test1' into 'test2'.

4. Save project.

Now when I take a look into saved project files I see still 'test1.xml' file but with changed property name="test2" inside.

I think that will be, after some time of developing and refactoring project, little uncomfortable in maintenance.

What do You think about it? There is way to keep files names the same as Test Cases names? Can I manualy change file names? There are somewhere references for thoese names?
