Is there a way to modify test options during the test run?

[kretschmannj]

Specifically, I'd like to update the value of skip_testcases_on_fail during the test run. Globally, I want the value to be true (the default). However, I have one particular test in which I'd like to set the value to false. I tried adding browser.options.skip_testcases_on_fail = false to the test but that didn't work. It's still using the default value.
