Requirement Coverage by two different groups?

Hello,

I am working on a project where two different and independent groups will create testcases that will cover the same requirements. How can ALM11 report the testcoverage achieved by each group? I can see, that cycles can be used for this as far as execution coverage is concerned. Is there a similar way to see the current coverage?

A simplified example: 

I have 5 Requirements R1..R5.

Testplan folder Groupe1 contains tests that cover requiremt R1 and R2

Testplan folder Groupe2 contains tests that cover requiremt R2 and R4 and R5

In the requirement module (or dashboard) I want to be able to see the following information:

- Which requirements are covered/not covered by Groupe1

- Which requirements are covered/not covered by Groupe2

- Which requirements are covered by both groups (this is "nice to have")

Any ideas? 

Best regards

Dominik
