Change owner of Test Run

When viewing 'My Page' there is a section called 'My Pending Test Runs' which displays all test runs which have been paused during execution.

Obviously, another user on the same project cannot see this run as it is displayed in 'My Page', but is there a way where:

a) I can change the ownership of test run so that someone else in the team can pick it up?

b) everyone else in the same project can view all paused/pending test runs so that they can pick them up?

Thanks

Nick
