Jira as Test Case Management Tool

I have reviewed several test case management solutions available for Jira such as:

• http://www.testandtry.com/2009/07/01/test-case-management-in-jira-1/
• http://confluence.atlassian.com/display/CONFEVAL/Customise+JIRA+For+Test+Case+Management

I was wondering if it is possible to expand this test case management solution even more. I am looking for a Jira solution to have:

• Requirements
• Test Cases (which go under Requirements)
• Test Reports (which go under Test Cases)

The links posted above only ignore the "Requirements" part and focus only on Test Cases and Test Reports. Every Test Case Management tool I have used before has these features like HP QualityCenter.

Is it possible to achieve this in Jira?

TIA
