Unit Test Sessions window - Clear Test Result

In the Unit Test Sessions, there's a tree containing the tests, grouped by whatever you've chosen to group by. (I usually use Group by Projects and Namespaces).

If you highlight a test or tests, you have a "Clear Test Result" option in the context menu.

If you highlight a group (a project or a namespace), you do not have a "Clear Test Results" option in the context menu.

It would be convenient if we could clear the test results for all of the tests by selecting the top-level groups.
